The Knights Armament 7.62mm QDC Open Brake Kit 3/4-24 For KAC QDC is purpose-built as the primary mounting interface for KAC 7.62mm QDC suppressors. Machined with an open, multi-port brake design, it helps manage recoil and muzzle rise while acting as a sacrificial blast baffle to reduce wear on the suppressor’s first baffle and extend service life. Compact and efficient, it threads directly onto 3/4-24 barrels and adds only a modest amount of length to the host rifle.

This muzzle brake is ideal for shooters who run their SR-25 or other properly threaded 7.62mm platforms both suppressed and unsuppressed. Its open architecture supports consistent performance during extended range sessions, training, or precision shooting, where repeatable mounting and stable handling matter. Backed by Knights Armament’s reputation for carefully engineered accessories and durable construction, the QDC Open Brake Kit integrates cleanly into the KAC ecosystem.
