QDB Muzzle Brake | Silent Steel
Backorder Notice: If the item is not in stock and marked as on backorder, the estimated waiting time is 2 months. Items in stock can be shipped out right away.
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 the user to adjust and eliminate horizontal barrel movement to the stronger hand direction.
Muzzle brakes are delivered with a shim kit and stainless steel M4 tuning screws.
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.
The taper at the front of the thread ensures solid lock-up and minimal, repeatable POI shift. It also effectively blocks fouling from entering the mounting surfaces.
