Knights Armament 7.62Mm Qdc Open Brake Kit 3/4-24 For Kac Qdc

The Knights Armament 7.62mm QDC Open Brake Kit is a muzzle brake designed specifically for the KAC QDC suppressor platform. If you're running a 7.62mm rifle with a 3/4-24 threaded barrel and plan to use Knights Armament suppressors, this brake serves as your primary mounting interface—it's the hard point that anchors your suppressor to your gun. Beyond its core duty, the open brake design works to reduce wear on the first baffle of your suppressor, which means longer service life and fewer trips in for maintenance. Whether you're shooting unsuppressed or swapping your can on and off, this brake is engineered to integrate seamlessly with the QDC quick-disconnect system.

QDC suppressors are known for rock-solid mounting and repeatable return to zero, and this brake is a critical part of that equation. The open architecture keeps things running cool and clean, which matters whether you're spending time at the range or in the field. At just over 3 ounces and adding less than 1.6 inches to your barrel, it's a compact addition that doesn't burden your sight picture or handling.

This is OEM Knights Armament hardware, not an aftermarket knockoff. If your rifle is threaded 3/4-24 and you're committed to the KAC ecosystem, the QDC Open Brake Kit is the right choice for a durable, reliable mounting solution.
