Best 300 Blackout Optics (2026): Red Dots, Holos and LPVOs

Here is the dirty secret about the 300 Blackout: it is two cartridges wearing one headstamp. A 110 grain supersonic load and a 220 grain subsonic load leave the same barrel and land in very different places, and the optic on top has to live with both. That is why picking the best optic for 300 blackout rifles is harder than picking one for a plain 5.56 carbine. The reticle that holds perfectly for one load is lying to you with the other.

So we did not build this list around one magic scope. There isn’t one. We built it around jobs. Short barrel carbine for the house. Suppressed rifle you run at night. Brush gun loaded with supersonic hunting ammo. Each pick below has a GunsAmerica Digest review behind it.

The quick version for 2026: a holographic sight is the best all-around answer for most 300 Blackout owners, because both-eyes-open speed matters more than magnification inside 100 yards, which is where most of these rifles live. Our reviewer put the Vortex AMG UH-1 Gen II on a Daniel Defense DDM4 PDW in 300 Blackout and pulled it off and back on between groups without seeing the point of impact move. That is the kind of boring result you want.

If you stretch supersonic loads on hogs or deer, a low power variable optic earns its weight. If you build a tiny pistol, a compact dot wins. And if money is no object, the Trijicon VCOG is the grown-up answer. Prices move, so every number below is either a current maker price or labeled with the year our reviewer saw it.

Buyer’s Guide: Choosing the Best Optic for 300 Blackout

Decide Which Load You Actually Shoot

This is the whole game. The 2014 version of this article ran a zero-yard zero comparison with a Barnes 110 grain TAC-TX at 2,500 fps and a 220 grain Sierra MatchKing at 1,050 fps. At 100 yards the supersonic bullet had fallen 3.00 inches below the bore line. The subsonic bullet had fallen 16.14 inches. At 200 yards it was 13.13 inches against 66.20. Those numbers came from a 2014 table, and your ammo will differ, but the lesson does not: no single bullet drop reticle covers both loads.

Pick a primary load and zero for it. If you swap loads often, a red dot or holographic sight with a known 50 yard zero and a memorized holdover for the other load is simpler than a BDC that is only correct for one of them. For load data, see our best 300 BLK hunting ammo tests.

Red Dot, Holographic or LPVO?

Red dots are small, light and run forever on one battery. Holographic sights are bigger, and the big ring is fast; the UH-1 review explains that a holo projects its reticle with a laser and mirror rather than bouncing an LED dot off the front lens. LPVOs give you 1x for close work and magnification for identifying what you are about to shoot, which matters a lot at dusk on a hog feeder. The tradeoff is weight. The Venom 1-6×24 on this list weighs 19.5 ounces before rings. The VCOG is 31.5 ounces per Trijicon.

Night Vision Settings

A lot of 300 Blackout rifles get bought for night work. If you run night vision, the optic needs dim settings that won’t bloom in the tube. The UH-1 Gen II has four NV settings, the MRO HD has four, and the VCOG has two. Check that before you buy, not after.

Size and Mounting on Short Guns

Short barrel rifles and AR pistols in 300 BLK put the optic close to your face and close to a short rail. Big LPVOs on a 9 inch gun look silly and handle worse. A compact dot or a holo keeps the package balanced. Quick detach mounts are worth having if you switch between a dot and a magnified scope on the same upper, and the UH-1 review is the proof that a good QD lever returns to zero.

Batteries

Weird batteries are a real cost. The EOTech 512 runs on AA batteries. So does the VCOG. The UH-1 Gen II uses a CR123A. The Venom uses a CR2032 for its illumination. AA cells are the easiest to find in a gas station at 2 AM, which is not a joke if this rifle is your truck gun.

Budget

The range here runs from the Venom 1-6×24, which our reviewer saw around $300 on the street in 2024, to the VCOG at a current Trijicon retail price of $3,136 and up. Spend money where you will feel it. On a house gun, that is a fast reticle and a good mount, not 8x glass. Pick your rifle first if you haven’t; our best 300 Blackout rifles guide covers ARs, pistols and bolt guns.

Best 300 Blackout Optics (2026): Our Picks

Vortex AMG UH-1 Gen II: Best for Night and Subsonic Work (2026)

The Huey Gen II is big. Over 3.9 inches long, 11 ounces, and it looks like it would survive being run over. Our reviewer mounted it on a Daniel Defense DDM4 PDW in 300 Blackout, fired groups between pulling and reinstalling the optic, and never saw a point of impact shift. He left it switched on for more than two months and did not change the battery. Four night vision settings and a 1 MOA dot inside the EBR-CQB ring make it a natural partner for a subsonic gun you shoot after dark.

Trijicon MRO HD 1×25: Best Compact Red Dot for Short Builds (2026)

Want a red dot that does not eat half your rail? The MRO HD is the answer a lot of short barrel owners land on. Our reviewer took it on a Texas turkey hunt, not a 300 BLK range day, and the reason he liked it applies anywhere: an aspherical lens that gave him a crisp dot despite astigmatism, which is not something most of us can say about most dots. You get a 2 MOA dot or a 68 MOA segmented circle, four NV settings, and a sight built to pair with Trijicon’s 3x magnifier when you want reach.

Read our full Trijicon MRO HD 1×25 review here.

Key Specs

• Type: Red dot, 1x, 25mm objective
• Reticle: 2.0 MOA dot or 68 MOA segmented circle with dot
• Brightness: 6 dot settings, 6 circle settings, 4 night vision settings
• Adjustment: 1/2 MOA per hash, 70 MOA range, capless
• Battery: housed in the brightness turret with a tethered cap
• Price: $969 MSRP with low mount and about $650 street when reviewed in 2021; check Trijicon’s page for current pricing

Pros

• Crisp dot for shooters with astigmatism, per our reviewer
• Segmented circle has known MOA gaps for rough ranging
• Small and light enough for SBRs and AR pistols
• Works with Trijicon’s 3x magnifier

Cons

• Expensive for a red dot
• Faint reflection of internals visible in some light
• Our review was not on a 300 BLK rifle

EOTech 512: Best Budget Holographic Sight (2026)

The 512 is the sight a generation of soldiers carried, and it earns a spot here for two plain reasons: a field of view few sights can match, and AA batteries. Our writer used one for most of his career, and our piece is honest that it is a first look and a history, not a long term test. It covers the bad years under L3, the 2015 thermal drift lawsuit, and the $25.6 million settlement. EOTech is back in private hands and won a SOCOM close quarters sight contract again. Our writer’s verdict: he trusts the design, and he is holding final judgment until the long test is done. That is the right amount of trust.

Read our EOTech 512 first look here.

Key Specs

• Type: Holographic, 1x
• Battery: AA
• Mount: Thumb screw attachment option
• Price: check EOTech’s page for current pricing

Pros

• Runs on AA batteries you can find anywhere
• Very wide field of view for close work
• Long service track record

Cons

• No long term Digest test yet
• Old school battery box design
• Brand history makes some buyers nervous

Vortex Venom 1-6×24 SFP: Best LPVO for Supersonic Hunting Loads (2026)

Here’s the catch first, because it matters. The Venom’s AR-BDC3 reticle is built for .223 and .308 loads, so its holdover marks will not match your 300 Blackout. Treat it as a crosshair with a dot, zero for your supersonic hunting load, and learn your own holds. What you get in return is a true 1x that our reviewer found fast with both eyes open, 6x for picking the right hog out of the sounder, and a scope that held zero on a .45-70 with a Vortex cantilever mount. His sample had a reticle blemish out of the box, and Vortex replaced it under warranty within two weeks.

Read our full Vortex Venom 1-6×24 SFP review here.

Key Specs

• Magnification: 1-6x, second focal plane
• Reticle: AR-BDC3, illuminated, 6 settings
• Tube: 30mm
• Adjustment: 1/4 MOA capped turrets, 140 MOA travel
• Eye relief: 3.7 in
• Length: 10.3 in
• Weight: 19.5 oz
• Price: $450 MSRP and about $300 street when reviewed in 2024; check Vortex’s page for current pricing

Pros

• True 1x low end
• Held zero under heavy recoil in our test
• Throw lever and sunshade in the box
• Low price for an LPVO

Cons

• BDC holds are not calibrated for 300 Blackout
• Illumination is not daylight bright
• SFP holds are only correct at 6x

Trijicon VCOG 1-8×28: Best Premium Optic for 300 Blackout (2026)

The VCOG is what happens when the Marine Corps writes the requirements. It is the Corps’ Squad Common Optic, and it costs like it. The reason it belongs on a 300 Blackout list is the first focal plane reticle: holds stay true at any magnification, and the reticle uses plain MOA or MRAD marks instead of a 5.56 BDC, so you can build your own subsonic and supersonic holds without doing math at 4x. Our reviewer shot the box with it on a .223 AR and found that every four clicks moved the bullet about an inch, just like the label says.

Read our full Trijicon VCOG 1-8×28 review here.

Key Specs

• Magnification: 1-8x, first focal plane
• Reticle: Segmented circle with MOA or MRAD crosshair dot
• Brightness: 11 settings, including 2 night vision
• Battery: AA, 633 hours at setting 6
• Housing: Forged 7075-T6 aluminum, waterproof to 66 ft
• Weight: 31.5 oz, per Trijicon
• Price: from $3,136 retail on Trijicon’s site as of November 2026, depending on mount and finish

Pros

• FFP reticle works for any load you zero
• Precise tracking in our box test
• AA battery
• Mount included

Cons

• Very expensive
• Heavy for a short rifle
• Our test rifle was a .223, not a 300 BLK

Best 300 Blackout Optics: Final Verdict

The best optic for 300 Blackout owners who run their rifle close is the one we put first. Buy the Vortex AMG UH-1 Gen II. It held zero through a remove and reinstall on a 300 BLK PDW, it plays nice with night vision, and a 50 yard zero plus a written holdover for your second load keeps it simple. If the gun is tiny, the Trijicon MRO HD gives you a crisp dot in a package that won’t overwhelm a short rail.

The EOTech 512 is the AA battery workhorse, with the caveat that our long test is still coming. The Venom 1-6×24 is the budget way to get magnification for supersonic hunting, as long as you ignore the 5.56 holds and learn your own. The VCOG is the best scope on this list and costs more than a lot of the rifles it would ride on.

Whatever you pick, zero it with the load you actually carry, then shoot the other load and write the difference down. Want more magnified options?
