The Super Quick Disconnect, or SQD attachment, for B&T's RBS suppressor has many features that have yet to be seen in any previous suppressor produced by B&T. The RBS SQD is an ingenious fusion of the reduced backpressure system (RBS) technology for which B&T is known for, and a totally new one-hand, 3-lug mounting system. The system is both smooth and fast to use. The new SQD mounting system is perhaps the fastest 3-Lug attachment system of its type. The new RBS SQD suppressor will fit all 9mm weapons featuring a 3-Lug barrel interface. This includes but is not limited to B&T’s APC9, SPC9, GHM9, as well as HK’s MP5, MP5K and variants with in-spec tri-lug barrels.
