QD Phantom Muzzle Brake

We designed this QD Muzzle brake to go with our new QD End Cap which is very similar to the ASR Adapter with a locking mechanism. We are currently expanding our product line so we will have more thread options coming soon. This brake is designed with a perforated end and has a bore size of 0.42″ for all thread sizes.

• Internal Thread of 1/2×28 or 5/8×24 (please email us for other thread requests)
