Cobalt Kinetics RCB-6 7.62mm Black Nitride Stainless Muzzle Brake - 5/8x24

The Cobalt Kinetics RCB-6 is a precision muzzle brake purpose-built for 7.62mm rifles. It is machined from stainless steel and finished in a rugged Black Nitride coating that resists corrosion, carbon fouling, and wear through hard use on the range or in the field.

Designed to tame the stout recoil of 7.62mm chambers, the RCB-6 uses a ported baffle geometry to redirect propellant gases upward and to the sides, reducing felt recoil and keeping the muzzle flat for faster, more accurate follow-up shots. The brake measures a compact 2.15" overall length, giving it a low-profile footprint that clears most standard handguards and muzzle devices while still delivering serious recoil management.

Installation is straightforward thanks to the 5/8x24 thread pitch. Drop it onto a properly threaded 7.62mm rifle barrel and the Cobalt Kinetics RCB-6 delivers the controlled recoil and reduced muzzle climb that serious shooters demand.
