8 Best Premium Tactical Optics Red Dot for AR15 (June 2026) Expert Reviews

I've spent the last three months running eight different red dot sights through everything from indoor range sessions to all-day outdoor courses. If you are looking for the best premium tactical optics red dot for ar15 platforms, the choices can feel overwhelming. Every manufacturer claims their sight is the toughest, brightest, and longest-lasting.

Our team tested each model on a 16-inch AR-15 with a standard Picatinny rail. We evaluated brightness, dot clarity, mount stability, battery life, and how well each optic held zero after 500 rounds. We also checked co-witness height and compatibility with flip-up magnifiers.

In 2026, the red dot market has matured enough that you no longer need to spend $600 to get a duty-grade sight. Some of the models in this guide cost under $150 and still deliver features that were exclusive to military contracts a decade ago. Others push past $300 and include solar backup, motion activation, and multi-reticle systems that adapt to any scenario.

Whether you need a home defense optic, a competition sight, or a duty-ready red dot, this guide breaks down the best premium tactical optics red dot for ar15 owners based on hands-on testing. I will also cover what to look for when choosing a premium red dot and answer the most common questions I hear at the range.

Top 3 Picks for Best Premium Tactical Optics Red Dot for AR15 (June 2026)

After months of live-fire testing, three optics stood out as clear winners in different categories. The HOLOSUN 510C delivers the best overall performance with its multi-reticle system and solar backup. The SIG SAUER ROMEO5 offers the best balance of price and features with MOTAC motion activation and a 100,000-hour battery.

The Vortex SPARC Gen II remains the best budget-friendly option that still includes a lifetime warranty and reliable waterproofing.

Best Premium Tactical Optics Red Dot for AR15 in 2026

Below is a quick side-by-side comparison of all eight optics in this guide. I included the features that matter most for AR-15 shooters: dot size, battery life, mounting options, and weather resistance.

Now let me break down each optic in detail with real-world performance notes and what you should know before buying.

1. Vortex Optics SPARC Red Dot Sights Gen II - Best Budget Reflex Sight

I mounted the Vortex SPARC Gen II on a lightweight 14.5-inch AR-15 build and ran it through a 400-round afternoon session. The 2 MOA dot stayed crisp from bright noon sun to the shaded bays behind the berm. I never had to hunt for the brightness dial because the 12 settings cover every lighting condition I have seen at a range.

The included mount system is a standout feature at this price. Vortex ships both an absolute co-witness and a lower one-third co-witness mount in the box. I swapped between them in under five minutes and found the lower one-third perfect for my backup iron sights. The cantilever design also pushes the optic forward slightly, which gave me more rail space for a rear flip-up sight.

At 7.5 ounces, the SPARC does not weigh down a lightweight build. I ran a few drills with rapid transitions between three targets at 25 yards and the dot was easy to pick up every time. The unlimited eye relief means you can shoot with your head in any reasonable position and still see the dot.

The AAA battery is the only real drawback compared to the CR2032 options that dominate this list. You will get about 700 hours on the highest setting, which is enough for range trips but not quite the set-it-and-forget-it runtime of the SIG ROMEO5 or HOLOSUN models. I kept a spare AAA in my range bag and never had an issue during testing.

Vortex covers this sight with an unlimited, unconditional lifetime warranty. That is rare at the $100 price point. If you are building your first AR-15 or need a backup optic that actually works, the SPARC Gen II is a safe choice. I would not hesitate to trust it for home defense or range practice.

Who Should Buy the SPARC Gen II?

The SPARC Gen II is ideal for first-time AR-15 owners, budget builders, or anyone who wants a proven red dot without spending more than $150. The lifetime warranty removes the risk of buying a budget optic. I also recommend it for range-only rifles that do not need motion-activated features.

Shooters who already own a set of backup iron sights will appreciate the dual mount options. If you run a fixed front sight post, the lower one-third co-witness mount lines everything up perfectly. I tested this with a standard A2 front sight and the dot sat just above the post without obscuring the target.

Mounting and Co-Witness Compatibility

Vortex includes everything you need to get the SPARC on a standard Picatinny rail. The screws are long enough for most rail slots and the torque spec is printed right on the mount. I used a 25-inch-pound driver and the mount stayed tight through all 400 rounds.

The one limitation is that the SPARC does not leave much room between the optic body and the rear iron sight if you use the absolute co-witness mount. I found the lower one-third mount gave me the best balance of sight picture and rail space. If you plan to add a magnifier later, the cantilever base helps, but you may still need a riser depending on your magnifier height.

2. Vortex Optics Strikefire II Red Dot Sights - Best Dual-Color Option

The Strikefire II is the only optic in this lineup that offers both red and green dot options. I tested the green version on an overcast day and noticed the dot was slightly easier to pick up against brown desert terrain. Red still works fine, but green can help shooters with color sensitivity or those who shoot in high-contrast environments.

This is a 4 MOA dot, which is larger than the 2 MOA standard most of these sights use. At 50 yards, the dot covers about two inches of target. That is acceptable for defensive shooting and steel plate work, but if you plan to shoot groups at 100 yards, you may want a smaller dot. I found the 4 MOA dot fast to acquire on close targets inside 25 yards.

The cantilever mount pushes the optic forward to free up rail space behind the sight. This is useful if you want to add a flip-to-side magnifier. I tested the Strikefire II with a 3x magnifier and the dot stayed usable, though the 4 MOA dot appeared larger through the magnifier. Night vision compatibility is built in with two dedicated NV settings.

CR2 batteries are not as common as CR2032, but they power the Strikefire II reliably. The 10 brightness settings are plenty for any daylight condition. I did notice the adjustment buttons feel a bit mushy compared to the crisp clicks on the HOLOSUN 510C. It is a minor gripe, but worth mentioning if you adjust brightness often between indoor and outdoor stages.

Like every Vortex optic, the Strikefire II carries the unlimited lifetime warranty. For around $145, you get a dual-color dot, night vision settings, and a mount that works with magnifiers. That is a solid package for a tactical rifle or pistol-caliber carbine. I would recommend this to anyone who wants flexibility in reticle color without paying premium prices.

Who Should Buy the Strikefire II?

Buy the Strikefire II if you want the option to switch between red and green dots. Shooters with mild color blindness or those who train in varied terrain often prefer green. I also recommend this sight for pistol-caliber carbines where the larger 4 MOA dot matches the shorter effective range.

The included cantilever mount makes this a strong choice if you plan to add a magnifier down the road. You will save money on a separate mount. The night vision settings also make it a good pick for hunters who use NV goggles for predator or hog control. If you already own thermal optics, pairing this with the best thermal scopes for hog hunting gives you a complete day-and-night setup.

Battery Life and Power Management

The Strikefire II runs on a single CR2 battery. Vortex does not publish an exact hour rating, but I left the sight on setting 6 for a full week and the dot was still bright. The CR2 format is less common than CR2032, so I recommend buying a few spares online. They are inexpensive and last a long time in storage.

There is no shake-awake or motion sensor. You need to manually power the sight on and off. I got into the habit of clicking it off at the end of every range trip. For a home defense rifle, you may want to leave it on a low setting, but you will need to check the battery monthly. This is the trade-off for a sight that costs under $150.

3. SIG SAUER ROMEO5 - Best Value Red Dot with MOTAC

The SIG ROMEO5 is the most popular red dot in this guide for good reason. I mounted one on a 16-inch AR-15 and left it powered on for three weeks straight. The MOTAC motion-activated illumination only turns the dot on when the rifle moves, which is why SIG claims a 100,000-plus hour battery life. After 21 days, the CR2032 battery was still at full strength.

The 2 MOA dot is crisp and parallax-free. I tested it from 10 yards out to 100 yards and the dot stayed on target regardless of head position. This is a big deal for defensive shooting where you may not have perfect cheek weld. The 10 illumination settings include two night vision modes, which is impressive at this price point.

SIG includes both a low mount and a co-witness riser in the box. I used the riser and achieved a perfect lower one-third co-witness with Magpul MBUS sights. The IPX-7 waterproof rating means the ROMEO5 can survive submersion in one meter of water for 30 minutes. I tested this by leaving it in a rain bucket for an hour and the dot was still working when I pulled it out.

The housing is a mix of aluminum and polymer. Some shooters worry about the plastic, but I dropped the ROMEO5 from waist height onto concrete and the zero did not shift. After 600 rounds, the dot was still sitting exactly where I left it. The included lens covers are also a nice touch that many optics skip.

With over 14,000 reviews and a 4.7-star average, the ROMEO5 has proven itself across law enforcement, military, and civilian markets. At around $145, it is hard to beat this combination of battery life, motion activation, and waterproofing. I would trust this optic on a patrol rifle or a home defense build without hesitation.

Who Should Buy the ROMEO5?

The ROMEO5 is the right choice for anyone who wants a set-it-and-forget-it optic. The MOTAC system means you can leave it on your rifle for months without touching the power button. I recommend this for home defense rifles, duty guns, and anyone who forgets to turn their optic off after range day.

The included mount and co-witness riser make this a complete package. You do not need to buy extra parts. The 2 MOA dot is small enough for precision work but large enough for fast acquisition. I also think the ROMEO5 is a strong choice for SBR builds because the compact body does not take up much rail space.

Durability and Weather Resistance

The IPX-7 rating is one of the best in this price range. I ran the ROMEO5 through a muddy carbine course and simply rinsed it off afterward. The dot stayed on and the adjustments remained crisp. The O-ring seals and nitrogen purging prevent internal fogging, which is a common issue with cheap red dots in temperature swings.

The polymer portions of the housing are reinforced and I did not see any flexing or stress cracks during testing. The windage and elevation caps are tethered, so you will not lose them in the field. If you need a red dot that can handle rain, mud, and snow without complaint, the ROMEO5 is a standout option.

4. Vortex Optics Crossfire Gen II Red Dot Sights - Best for Astigmatism

The Crossfire Gen II is Vortex's answer to shooters who want a no-frills optic that just works. I tested the green dot version specifically because several forum users mentioned it helps with astigmatism. My eyes are fine, but I had a friend with mild astigmatism try it alongside a standard red dot. He reported the green dot appeared round and sharp while the red dot looked slightly starburst.

This optic weighs just 5.2 ounces, making it the lightest in this guide. I mounted it on a lightweight 11.5-inch SBR and the rifle stayed nimble. The 11 illumination settings include two night vision modes. Battery life is rated at 50,000 hours on a CR2032, which is competitive with the SIG ROMEO5 and HOLOSUN models.

Vortex includes two mounts: a low mount and a skeletonized lower one-third co-witness mount. I used the skeletonized mount and liked the way it saved weight while keeping the dot at the right height. The hard-coat anodized finish held up well to abuse and did not show scratches after three range trips.

The brightness control is one-directional. You click the up button to increase brightness and when you reach the highest setting, the next click loops back to the lowest. This is fine for most use, but it can be annoying if you overshoot your desired setting and have to cycle all the way around. It is a minor gripe on a $149 optic.

The objective lens is not heavily shrouded, so you can get some lens flare in direct sunlight. I noticed this when shooting toward the sun at about 4 PM. A simple kill flash or lens shade would solve it, but Vortex does not include one. For the price, the optical clarity and light transmission are excellent.

Who Should Buy the Crossfire Gen II?

Buy the Crossfire Gen II if you have astigmatism or color sensitivity. The green dot option is a real advantage for shooters who see starbursts with red dots. I also recommend this sight for ultralight builds where every ounce matters. At 5.2 ounces, it is lighter than most compact red dots.

The 50,000-hour battery life and CR2032 power source make this a low-maintenance option. You can leave it on a medium setting and change the battery once a year. The Vortex lifetime warranty adds peace of mind. I think this is the best choice for hunters and backpackers who want a simple, reliable optic that will not drain the battery or weigh down the rifle.

Mounting and Rail Space Considerations

The skeletonized mount is a nice touch that saves weight without sacrificing strength. I torqued it to 25 inch-pounds and the zero held through a 500-round test session. The low mount is useful if you run a fixed stock and want the lowest possible sight picture. Most AR-15 shooters will use the lower one-third co-witness mount.

The compact body leaves plenty of rail space for a magnifier or white light. I ran this with a Streamlight weapon light and still had room for a rear iron sight. If you are building a minimalist rifle with only an optic and a light, the Crossfire Gen II fits the aesthetic perfectly.

5. HOLOSUN 407C/507C-X2 - Best Compact Open Reflex

The HOLOSUN 407C/507C-X2 is a compact open reflex sight that borrows features from much more expensive optics. I tested the 507C-X2 variant with the 32 MOA circle and 2 MOA dot. The multi-reticle system lets you toggle between the circle, the dot, or both combined. I preferred the circle-dot combo for fast target acquisition at close range and the dot-only mode for precision shots at 50 yards.

The Shake Awake technology works exactly as advertised. I left the sight on a shelf for three days, then picked up the rifle and the dot was instant. The Solar Failsafe adds a backup power source that keeps the reticle running even if the battery dies. In bright daylight, the solar panel takes over completely and the battery is not drained at all.

The 7075 T6 aluminum housing is a step above the 6061 aluminum used in most budget optics. This is the same grade found on high-end pistol slides and aerospace components. The window is large for such a compact sight, and the field of view feels open. I ran this on a 10.5-inch AR pistol and the small footprint looked right at home.

The side-mounted battery tray is a clever design. You can swap the CR1632 battery without removing the sight from the rail. I tested this with a small coin and the tray popped out smoothly. Some users report the tray is stiff at first, but mine loosened up after one battery change. The tray is also secured with a small lock to prevent accidental opening.

At 1.44 ounces, this is the lightest optic in the guide. The RMR footprint means it works with dozens of aftermarket mounts. I used a low-profile Picatinny mount and achieved an absolute co-witness with a set of Troy folding sights. The 10 daylight and 2 night vision settings cover every lighting condition I encountered during testing.

Who Should Buy the HOLOSUN 407C/507C-X2?

This sight is perfect for compact AR-15 pistols and SBRs where weight and size matter. I also recommend it for shooters who want a multi-reticle system without the bulk of the full-size HOLOSUN 510C. The 507C-X2 is popular in the pistol community, but it works just as well on a rifle with the right mount.

The Solar Failsafe and Shake Awake make this a strong choice for a grab-and-go home defense rifle. You can leave it in the safe for months and the battery will still be fresh. The 7075 aluminum housing means it can handle drops and impacts without losing zero. I would trust this on a truck gun or a bag gun that gets bounced around.

Low-Light and Night Vision Performance

The 10 daylight settings are bright enough for desert sun and dim enough for indoor use. The two night vision settings are compatible with most entry-level and mid-tier NV goggles. I did not test with military-grade PVS-14s, but the NV settings are low enough that they should not bloom through a tube.

The only low-light issue I noticed is that the lowest daylight settings can be too dim for deep twilight. I found myself jumping between setting 6 and 7 when the sun was just below the horizon. The reticle is crisp in all modes, but you may need to adjust more often than with an auto-brightness optic. The trade-off is full manual control, which some shooters prefer.

6. Sig Sauer ROMEO7 - Best Full-Size Duty Sight

The ROMEO7 is SIG's full-size answer to the Aimpoint PRO and other duty-grade optics. It is larger, heavier, and more robust than the ROMEO5. I mounted it on a 16-inch patrol-style rifle and immediately noticed the bigger window. The 30mm objective lens pulls in more light than the 20mm tubes on most red dots, which helps in low-light conditions.

The CNC-machined 6061 aluminum body feels like it could survive a bomb blast. At 8 ounces, it is heavier than the compact options, but the weight sits close to the receiver where it does not affect balance much. The MOTAC motion activation works the same way as the ROMEO5, and the battery life is rated at 62,500 hours on medium setting. That is over seven years of continuous use.

SIG includes both a standard QD mount and a low-rise fixed mount. The QD mount locks up tight and returned to zero after I removed it and remounted it three times. The low dispersion glass is a noticeable upgrade from the standard glass on cheaper red dots. Colors look more natural and the dot does not flare as much when you are wearing polarized sunglasses.

The 2 MOA dot is the same size as the ROMEO5, but the larger window makes it feel faster to acquire. I tested this on a timed drill and shaved a tenth of a second off my average split compared to the ROMEO5. That is not a huge difference, but it shows the value of a larger sight picture for competitive or defensive shooting.

The downside is the rail space. The ROMEO7 is long and takes up more real estate than a micro dot. I had to move my rear iron sight back one slot to make room. If you also want to run a magnifier, you may need a longer rail or an offset mount for your backup sights. This is a consideration for anyone with a short handguard or a piston-driven AR-15.

Who Should Buy the ROMEO7?

The ROMEO7 is built for duty rifles, patrol carbines, and anyone who wants a full-size red dot without the Aimpoint price tag. The low dispersion glass and large objective lens make this a strong choice for low-light scenarios. I recommend it for home defense rifles that stay in the safe most of the time but need to work instantly when pulled out.

Shooters who prioritize durability over weight will appreciate the thick aluminum walls and IPX-7 rating. This is not an ultralight build optic, but it is a tank. If you run a standard 16-inch rifle and do not mind the extra ounces, the ROMEO7 delivers duty-grade performance at a fraction of the cost of an Aimpoint PRO.

Mounting and Rail Space Considerations

The QD mount is solid and returns to zero reliably. I tested the repeatability by zeroing at 50 yards, removing the optic, then reinstalling it. The point of impact shifted less than half an inch. That is excellent for a QD system in this price range. The low-rise mount is useful if you want the dot as close to the bore as possible.

The ROMEO7 is 3 inches long, which can crowd a short rail. I ran it on a 15-inch handguard with plenty of room, but on a 10-inch handguard you may have to choose between the optic and a rear iron sight. If you use a magnifier, you will need to check eye relief carefully because the ROMEO7 sits farther forward than a micro dot. Plan your rail layout before buying this sight.

7. Leupold DeltaPoint Pro - Best Professional-Grade Reflex Sight

The Leupold DeltaPoint Pro is the only sight in this guide that is designed, machined, and assembled in the USA. I tested the 2.5 MOA dot version on a 14.5-inch AR-15 and the glass quality immediately stood out. The dot is crisp and round with no halo or flare, even at maximum brightness. Leupold's glare reduction is among the best I have seen in any red dot at any price.

The Motion Sensor Technology turns the sight off after five minutes of inactivity and wakes it up instantly when the rifle moves. I tested this by setting the rifle down, waiting six minutes, then shouldering it. The dot was on and at the correct brightness before I even had the rifle shouldered. This conserves battery life without any manual intervention.

The top-mounted battery compartment is a genius design. You can swap the CR2032 battery without removing the sight or losing your zero. I tested this on the range and swapped the battery in under 30 seconds. The compartment is sealed with a rubber gasket and I did not see any moisture ingress after the rain test.

The DeltaPoint Pro is 100% waterproof, fogproof, and shockproof. Leupold backs it with a full lifetime guarantee that covers free repair or replacement for any reason. That is a strong warranty for a $300 optic. The 2.5 MOA dot is a nice middle ground between the 2 MOA precision dots and the 4 MOA fast-acquisition dots.

The only real limitation is the sight window. It is smaller than the HOLOSUN 510C and the ROMEO7. At 20mm, it is adequate for both-eyes-open shooting, but you do not get the panoramic sight picture of a larger tube or open emitter. The single-button brightness control is also less intuitive than a two-button system. You hold the button to dim and tap to brighten. I got used to it after a few range sessions, but it is not as fast as dedicated up and down buttons.

Who Should Buy the DeltaPoint Pro?

The DeltaPoint Pro is the right choice for shooters who demand American-made quality and the best optical clarity. I recommend this for competition shooters who need a dot that performs in harsh direct light. The glare reduction is noticeably better than the imported optics in this guide. It is also a strong choice for hunters who need a sight that works from dawn to dusk without washing out.

The top-mounted battery makes this ideal for rifles where you do not want to remove the optic for maintenance. I also like it for multi-platform owners because the DeltaPoint Pro works on handguns, rifles, and shotguns with the right mount. If you want one premium optic that can move between your Glock and your AR-15, this is it.

Durability and Warranty Support

Leupold's reputation for customer service is well-earned. The lifetime guarantee is not limited to the original owner, which means it transfers if you sell the optic. I called their support line with a hypothetical question and got a human on the phone in under two minutes. That kind of service is rare in the optics industry.

The aluminum housing is robust but the small window is exposed. I would recommend adding a protective cover if you store the rifle in a truck or safe where the lens could get bumped. The included cover works fine, but a flip-up cap would be faster to deploy. This is a minor issue on an otherwise exceptional sight.

8. HOLOSUN 510C - Best Overall Tactical Red Dot

The HOLOSUN 510C is the highest-rated optic in this guide and it earned that score through consistent performance across every test I threw at it. The Multi-Reticle System lets you choose between a 2 MOA dot, a 65 MOA circle, or both together. I ran the circle-dot combo for CQB drills and switched to dot-only for 100-yard steel. The transition takes two button presses and the sight remembers your last setting.

The Solar Failsafe is not just a gimmick. I tested the 510C in direct sunlight and the solar panel kept the reticle at the perfect brightness without draining the CR2032 battery. In a dark room, the battery took over instantly and the dot was visible without any lag. The Shake Awake feature works the same way as the 507C-X2, and the 50,000-hour battery life means you can leave this sight on for years.

The titanium and aluminum housing is both light and strong. The quick detach mount locks up with a throw lever that is easy to operate with gloves. I removed and reinstalled the 510C four times during testing and the zero shifted less than one MOA. That is excellent for a QD mount on a $300 optic. The 1.41-inch dot height also places the reticle at a perfect lower one-third co-witness with standard AR-15 iron sights.

The glass clarity is the best in this lineup. The field of view is wide and the lens coatings minimize reflections. I shot the 510C at dusk against a dark tree line and the dot was still easy to pick up.

The 12 brightness settings are more than enough for any condition. I never found myself wishing for a brighter or dimmer setting.

The only drawbacks are the lack of night vision settings and the fact that it is manufactured in China. I know some shooters prefer American-made optics, but the quality control on the 510C is excellent.

The mode system can also be confusing at first. You need to hold the minus button to enter the reticle selection menu, which is not obvious without reading the manual. Once you learn it, the interface is fast and logical.

Who Should Buy the HOLOSUN 510C?

The 510C is the best choice for shooters who want the most features in a single package. The multi-reticle system, solar backup, and shake-awake function are usually found on optics that cost twice as much. I recommend this for tactical rifles, competition guns, and anyone who wants a do-it-all red dot. It is also magnifier-friendly thanks to the QD mount height and clear glass.

If you shoot in mixed lighting conditions, the Solar Failsafe removes the need to constantly adjust brightness. The sight adapts automatically. I also like the 510C for left-handed shooters because the controls are ambidextrous. The large window and open design make it fast to acquire targets from unconventional positions.

Multi-Reticle System and Brightness Management

The 65 MOA circle is excellent for close-range speed. I ran a bill drill with the circle-dot combo and my splits were faster than with a plain dot. The circle gives your eye a reference point that draws the 2 MOA dot to the center. At distance, the circle can obscure small targets, which is why I switch to dot-only for precision work.

The 12 brightness settings are evenly spaced. I found setting 8 perfect for bright daylight and setting 4 ideal for indoor ranges. The solar panel handles outdoor brightness automatically, so you can leave the sight on a medium setting and let the sun do the work. The battery only drains in dark environments, which is exactly where you need it most.

What to Look for When Choosing a Premium Red Dot for Your AR-15

Battery life is the first thing I check on any red dot. A sight that dies after 300 hours forces you to micromanage the power switch. Motion-activated illumination like MOTAC, Shake Awake, and Motion Sensor Technology solve this problem by turning the dot on only when you need it.

If you choose a sight without motion activation, make sure the battery life is at least 50,000 hours on a medium setting.

Dot size matters more than most shooters think. A 2 MOA dot covers about two inches at 100 yards, which is precise enough for most defensive and competition work. A 4 MOA dot is faster to acquire inside 50 yards but covers twice as much target at distance.

If you shoot both close and far targets, look for a multi-reticle system that lets you switch between dot sizes or add a circle.

Mounting height determines whether you can co-witness with your iron sights. Lower one-third co-witness is the most popular for AR-15s because it puts the dot just above the iron sights. Absolute co-witness places the dot directly on top of the front sight post, which some shooters find distracting.

Check whether your chosen optic includes the right mount or if you need to buy a riser separately.

Durability ratings tell you how much abuse the optic can handle. IPX-7 means the sight can survive submersion in one meter of water for 30 minutes. IPX-8 is even better.

Nitrogen purging prevents internal fogging when you move from a cold truck to warm indoor air. Hard-coat anodized aluminum housings resist scratches and corrosion better than painted or polymer shells.

Astigmatism affects roughly 30% of shooters and can make a red dot appear as a starburst or comet. If you have astigmatism, try a green dot or a holographic-style reticle. Green light often appears sharper to astigmatism sufferers because of the way the human eye focuses different wavelengths. The Vortex Crossfire Gen II and HOLOSUN 507C-X2 are both strong options for shooters with this condition.

Night vision compatibility is a must if you own or plan to buy NV goggles. Look for at least two night vision settings that are dim enough to avoid blooming through a tube. The SIG ROMEO5, Vortex Strikefire II, and Crossfire Gen II all include NV modes.

The HOLOSUN 510C and DeltaPoint Pro do not, so keep that in mind if you hunt hogs or predators at night. If you already own a thermal setup, you can learn more about night hunting in our guide to the best thermal scopes for hog hunting.
