Much of what AAC is producing in 2022 and beyond is direct thread and universal thread adapters, but for those customers who have legacy 5T Blackout style muzzle devices, the STAMP adapter fits on the AAC 51T flash hider or muzzle brake and then inserts into a suppressor from many brands with a universal, or sometimes called Bravo, hub or Omega threaded suppressors, where the internal threads are 1.375"-24.
The S.T.A.M.P. (Spring Tensioned Accessory Mounting Platform) enables users to quickly and easily install or remove a silencer to or from a 51T muzzle-device-equipped host firearm with one hand, using an intuitive motion and gross motor skills. The S.T.A.M.P. Mount features an internal ACME thread and a spring tensioned internal feature that provides solid, wiggle-free engagement with 51T muzzle devices. Secondary retention is provided by a coil-spring tensioned, toothed pawl with a textured thumb pad. The pawl axis pin is easily removable in the event the teeth of the pawl wear and pawl replacement becomes necessary.
