Smith Enterprise 6.8/7.62 Muzzle Brake with 5/8x24 RH threads
This new Smith Enterprise muzzle brake is designed to fit 6.8mm and 7.62mm military style rifles that have the standard 5/8x24 TPI RH threads. It is supplied with a locking jam-nut that allows the shooter to easily index the muzzle brake so that the top ports point straight up. Once in position, the jam nut is tightened against the back of the muzzle brake to lock it into position. Its multiple side and top ports are designed to effectively reduce recoil and muzzle climb. This is a proven recoil reducing design manufactured by Smith Enterprise Incorporated (SEI). It has the same 14 gas ports precision machined into the sides and top of the brake just like the very effective SEI M14 USCG muzzle brake and the SEI M1 Garand muzzle brake. There are no downward facing ports to minimize dust signature from the prone position. This brake is not suppressor capable.
Machined from super tough 8620 chrome moly steel and hardened to a core hardness of 36-38 HRC and a surface hardness of 55-58 HRC. The lock nut is also made from 8620 steel and is heat treated to 36-38 HRC all the way through. Brake and jam nut have a very hard, durable and good looking matte black Salt Bath Nitride finish.
Length: 2.0", Diameter: .90", Weight: 3.6 ounces, Thickness of Jam Nut: .20".
