Precision Armament’s M4-72 Severe-Duty Compensator! With all of that said, our recoil reduction winner is… drum roll please… Averages of multiple measurements were, however, rounded to 4 decimal places and recoil reduction percentages were rounded to 2 places. Eight 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 was only 0.1470 inches. The results were highly 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 goes out the muzzle, I proceeded to “sled test” all of the brakes/comps plus controls of bare muzzle and 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 aesthetics, price, flash, concussion, etc. 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 in flash, but this test was specifically designed only for measuring recoil - rearward energy. Usually the boogeyman is “muzzle rise” (which I believe is usually just the natural byproduct of rearwards recoil energy anyway). A steady muzzle means steady sights, and steady sights means fast, accurate shooting. Recoil Testingįor many brakes and comps, felt recoil reduction is only one goal, with the other primary design intention being the reduction of muzzle movement in any other direction.

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. 308 brake test HERE. You may also be interested in the AR-15 Drop-In Trigger Roundup HERE. The first 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. Hopefully both muzzle device shootout installments will help narrow down the shopping list.Īdditionally, a flash hider-specific test is coming in a few weeks!ĮDIT: This is the second test I did, but it hasn’t been the last.

In addition to the objective recoil test, all brakes are listed alphabetically below and I have stated my frank opinion on machining, fit/finish, and utility plus included any items of note as well as the relevant stats for each. Again though, recoil reduction is only one of many variables worth considering - and how they’re each weighted is a matter of personal opinion and/or intended use - when choosing which muzzle device will adorn one’s rifle.
