The Dead Air DTB Direct Thread Brake Mount in 1/2-28 from Dead Air Silencers (brand part no. DTB323HT) is both a muzzle brake and a direct-thread adapter for a Dead Air suppressor. As a brake it reduces felt recoil for faster follow-up shots, and it directs gas into the suppressor blast chambers to cut focused erosion on the baffles. The body is 17-4PH stainless steel with a black nitride finish. This 1/2-28 version has a 9mm bore.
