DELTA AR15 Muzzle Brake
Our in-house designed DELTA muzzle brake comes standard on all of our DELTA-series complete rifles and complete uppers. These 5.56MM / .223 muzzle brakes feature a total of 15 gas ports, in groups of three, offset by 72 degrees. The design also consists of a recessed exit port and is designed with impact functionality in mind. The design is extremely effective at reducing recoil and muzzle rise, while not adding an exorbitant amount to the sound signature.
The muzzle brakes are machined from 4140 steel, heat-treated to 55RC, and then coated using Ferritic Nitrocarburizing, which leaves it a nice satin black finish and raises the final hardness to 60+RC. They are also threaded to the standard AR15/M4/M16 muzzle threads of 1/2-28 UNEF.
When installing this muzzle brake, use the included crush washer to time the muzzle brake to have a port at 12 o'clock, and no ports at 6 o'clock.
