Full Description 

High-performance competition muzzle brake engineered for CMMG 5.7×28 platforms and any firearm with a 1/2″x28 TPI threaded barrel. This short-profile brake (1.58″) is CNC precision machined from hardened 8620 tool steel and finished in durable black oxide for long-lasting performance.

Side and top ports efficiently redirect propellant gases to dramatically reduce recoil, muzzle rise and flash — delivering better control and faster follow-up shots. Solid machined construction and heat treatment provide strength and longevity suitable for competition and tactical use.
