In the past, we compared 35 different AR-15 muzzle devices. That shootout, like this one, pitted them against each other in a sled test to see which reduced rearwards recoil energy the most. However, this time around there are [almost] no flash hiders, linear compensators, or other devices not actually designed to reduce recoil. A total of 37 brakes and compensators joined in the fun for roundup part deux, although 8 of them are carry-overs from the first test, including the previous recoil eliminating winner. . .
