The 300 AAC Blackout (300 BLK aka 300 Blackout) is one helluva spherical. It’s arguably the one AR-type cartridge able to working suppressed or un-suppressed – supersonic or subsonic – with out ever altering your rifle’s or pistol’s configuration. It accomplishes this with a variety of masses. Gentle 125-grain masses are able to offering wonderful supersonic efficiency with accuracy past 300 meters. Heavy masses (like Sig’s 205-grain hunting rounds) can punch severe holes up shut with wonderful sound signatures ran by means of a can. However swapping supers for subs, or vice versa, presents some concentrating on challenges. The ballistics range wildly between these masses, making the everyday optic’s zero considerably ineffective. That’s the place the Trijicon ACOG 4×32 BAC (300 Blackout) optic comes into play and we’re going to evaluation it right here in the present day!

The ACOG BAC Reticle
The ACOG BAC’s reticle is what makes this optic actually shine, particularly with regards to 300 BLK. The diamond purpose factors present bullet-drop compensation for traditional subsonic (left) and supersonic (proper) masses.
To make use of this reticle precisely, Trijicon says you could zero at 100 yards utilizing 115-grain supersonics. Typically, ballistics of most supers and subs will carry out precisely with holdovers as soon as this zero is achieved.
How the Reticle Works
For subs, every diamond is ready to compensate at zero, 50 yards, 100 yards, 150 yards, and 200 yards. Supers are set to compensate for zero, 200, 400, 500, and 600 yards alongside the identical airplane. I’ve examined how properly the holdovers work with each 150-gr. Hornady FMJs, and 220-gr. OTMs from Black Hills, as these two masses are likely to signify the most typical tremendous and sub weights on the everyday shelf. They’re fairly correct. They’ll by no means be 100%; there are just too many grain weights obtainable inside each camps. But it surely will get the job executed on the everyday 12″ goal.
Illumination on battery energy is okay. I run on the 4th brightness setting. It’s satisfactory for shiny daytime capturing within the open deserts oh Utah. Settings #5 and #6 present a number of bloom and wash out the middle reticle, however you most likely received’t ever have to run it this shiny. Coloration choices embody yellow, crimson, and inexperienced. I want crimson for low-light circumstances.
Trijicon says at brightness setting #4, you’ll get round 12,000 hours of battery life, or 500 days of steady use. I want working off battery. The ACOG’s authentic fiber optic brightness is reliant on ambient mild. I discovered myself utilizing the outdated “cover-it-with-tape” methodology to cut back brightness on my service-issued ACOG. The ACOG is on the market with this similar BDC reticle for .223 and 5.56 rifles.
Anybody who’s used an ACOG is aware of they’re one of many hardest optics you should buy. This iteration is not any completely different. It sports activities the identical one-piece, cast aluminum housing and (beneath my janky Duracoat paint job) the everyday matte black, rubberized coating that by no means appears to put on or fade.
One thing I’ve needed for years: The ACOG BAC runs off good ole’ AA battery energy. Improbable. A single cell is required, with a water-proof O-ring sealing the knurled flathead screw cap.
Turrets and Changes
The turret caps additionally sport waterproof O-rings, in line with this optics IP69 submersible score. Windage and elevation each modify 2 MOA, or 2″ per click on at 100 yards. Clicks are tactile and really feel stable; there are not any fancy zero stops. However then once more, this a “set-it-and-forget-it” sort of optic.
The brightness adjustment knob is massive and knurled. It feels stable, with small detents alongside white labels to point every brightness setting. The optic powers on and off between settings, which implies you don’t have to cycle all the way in which up and again right down to get to your most well-liked stage of brightness. A handy little design selection.
The RMR mount supplies nice lock-up. I’ve eliminated my ACOG a couple of times to briefly accommodate different scopes. I discovered there was no have to re-zero after re-indexing and clamping it again down.
With the RMR mount biased ahead, ample clearance is offered beneath the rear lens for grabbing your charging deal with. That is with the mount seated as ahead atop the everyday flattop rail because it’ll go.
What’s To not Like?
Take a second have a look at that image above, and also you’ll notice I’m working no backup irons. Even with the optic pushed as ahead because it’ll go, there’s simply not sufficient clearance on the everyday AR’s higher receiver for flip-up rear sights. You might spend some additional doe and seize a micro-red dot that mounts atop the rear lens. However they’re costly a bit too “tacticool” for my style. So, in case you like capturing irons, you’ll end up unscrewing that RMR mount very often. That is the one foible I’ve discovered working this optic.
The Hog Hunter’s Companion
Used alongside a top quality barrel (like my 10.3″ Triarc TRACK 2.0) and a good suppressor, the 300 Blackout ACOG 4×32 BAC is the right scope quick acquisition and accuracy with all masses. It’s a superb hog scope, and arguably probably the most handy piece of glass for these of us who get pleasure from capturing supers and subs equally. Seize one for your self, zero and familiarize, after which set up a hog hunt in Texas for some severe enjoyable.
