B&T has found the sweet spot between size, weight, diameter, as well as sound and flash reduction to provide users with many years of reliable service. The RQD (Ratchet Quick Disconnect) submachine gun suppressor is a hybrid of the most successful 9mm suppressors that B&T has been producing for many years and is compatible with all 3-Lug muzzle mounting systems inclusive of our APC9-series, HK MP5 and the new Beretta PMX — just to name a few. The RQD submachine gun suppressor has borrowed our proven B&T ratchet system found on our renowned ROTEX-series. This system provides a rock-solid attachment method that will not require any hand tightening, even after hundreds of round fired. The satisfying click-click-click of the ratchet exemplifies quality and precision machining. This design enables the user to mount and unmount the suppressor by using only one hand.
