The Knights Armament 7.62mm QDC Open Brake Kit 5/8-24 For KAC QDC is a purpose-built muzzle brake designed to serve as the primary mounting interface for KAC 7.62mm QDC suppressors. Machined from durable Inconel with a black finish, its open-port design helps redirect gas to manage recoil while shielding the suppressor’s first baffle to extend service life.

This brake is ideal for shooters running .30-caliber rifles such as 7.62x51 NATO or .308 Winchester who want a secure, repeatable suppressor mount without adding unnecessary bulk. With standard 5/8-24 threads, it installs on most modern 7.62 barrels and adds only a modest amount of length, making it well suited for range use, training, and precision shooting where consistency and control matter. The design reflects Knights Armament’s reputation for careful engineering and dependable performance in premium firearm accessories.
