The Super Quick Disconnect (SQD) attachment for B&T’s RBS9 suppressor features capabilities not seen in any previous B&T suppressor. The RBS9 SQD is an ingenious fusion of the reduced backpressure system (RBS) technology for which B&T is known and a new one-handed, 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, and GHM9, as well as HK’s MP5, MP5K, and variants with in-spec tri-lug barrels.
