QD Muzzle Brake
Silent Steel QDB Muzzle Brake is a suppressor mounting 2 chamber muzzle device, which provides very good muzzle control and recoil management. Closed bottom construction combined with upward biased V-shape venting, effectively eliminates both muzzle rise and dust signature. Tuning ports on both sides allow user to adjust and eliminate horizontal barrel movement to stronger hand direction. Muzzle brakes are delivered with shim kit and stainless steel M4 tuning screws.

More info:
Silent Steel Boltlok (QDB) muzzle devices are compatible with both Silent Steel Boltlok (QDB) and QD suppressors. When using QD suppressors, an o-ring is required for secure locking. However, the o-ring should not be used with Boltlok suppressors.
Taper at the front of the thread ensures solid lock up and minimal/repeatable POI shift and it also effectively blocks fouling from entering the mounting surfaces.
