It also does “tuning fork” just a little bit (the tines ring). Machining is very crisp and precise, and the finish looks great (it’s either a higher gloss nitride or AAC’s “SCARmor”).ĪAC says it’s “the best of both worlds in a truly compromise-free design,” and I think it looks great but it was far from the best brake and both slow-mo shots showed some fire and flash. Each is angled rearwards and matches up with one of the gaps between the three flash hiding tines. It’s sort of a single-chamber brake but, instead of a port on each side, it has three small ports. The BRAKEOUT is supposed to combine the best features of a conventional muzzle brake along with excellent flash suppression. Also available for 7.62.Ĭlick here to jump to its point in the video. If one has no use for the suppressor attachment feature and isn’t drawn to it for its unique looks, there are smaller and lighter options. It’s a good looking and effective two-chamber brake. I noted many obvious errors on manufacturers’ sites so chose not to blindly trust their info across the board.Ĭlean machining and a low gloss nitride finish make for an attractive brake that doubles as a fast-attach mount for AAC sound suppressors. All stated weights and dimensions are as measured by me. Click any of these (or any other photo in the write-up) to see them full-size: Also, thanks to TTAGer NotoriousAPP’s awesome data skillz and willingness to help out, we have not only my boring tables but also some cool charts to show as well. I was going to force y’all to watch the video to see the results (you know, I make like three cents every time the video ad is clicked), but I couldn’t bring myself to do it. That’s a 73.84% reduction for you folks keeping score at home. With a bare muzzle, it slid 9.175 inches. With this bad boy on the muzzle, the test rig slid back an average of 2.4375 inches. Precision Armament’s M4-72 Severe-Duty Compensator! With all of that said, our recoil reduction winner is… drum roll please… Seven brakes did multiple shots with the exact same result each time.įor the record, I measured in 1/16-inch increments and chose not to round when converting that to decimal measurements later. In fact, the average of the extreme spreads - difference between shortest and farthest result - for everything in the test (including bare muzzle and A2, which were the least consistent of all) was only 0.1943 inches. The results were surprisingly repeatable and consistent.

With my gas piston AR-15 strapped in a rest and the gas block turned to “off,” which means the action remains locked shut and 100% of the gas going out the muzzle, I proceeded to “sled test” all of the muzzle devices plus control measurements of the bare muzzle and a standard A2 birdcage. 223/5.56 here, and many prospective purchasers will put recoil reduction at the bottom of their list behind other considerations like reducing flash and concussion. Keep in mind that we’re also talking about the fairly minor recoil of.
The slow-mo footage for each device in the following video does show some noticeable differences in up/down muzzle movement as well as flash, but this test was specifically designed for measuring recoil - rearward energy. For most brakes and comps, felt recoil reduction is only one goal anyway, with the other primary benefit being the reduction of muzzle movement in any other direction.
dedicated flash hiders or a linear compensators). Some balance recoil management with flash hiding, and some have no recoil reduction consideration whatsoever (e.g.

As a Patron you can also get free stuff, join live streams, gain early access, and more.įirst, a quick note: not all of these muzzle devices are brakes/comps, or were otherwise designed to mitigate recoil. Please consider supporting this sort of testing via my Patreon page. I also want to do another AR-15 trigger roundup (component triggers this time) and a couple of flashlight roundups (tactical and gun-mounted). But I have a lot of brakes to round up for that and the funding is low. I’ve purchased air pressure sensors designed to log blast waves so we can compare the amount of concussion each muzzle device generates, and these will be used in test four. These tests are expensive, but I’d love to do more. You may also be interested in the AR-15 Drop-In Trigger Roundup HERE. The second 5.56 muzzle brake test is HERE, the third is HERE, the first 5.56 flash hiding test HERE, the second 5.56 flash hiding test HERE, and the first. EDIT: This is the first test I did, but it hasn’t been the last.
