The Advanced Armament Corp 51T S.T.A.M.P. mount adapter delivers fast-attach capability for shooters running legacy and current-production 51 Tooth muzzle devices. Built for the Ranger Series suppressor lineup, this Spring Tensioned Accessory Mounting Platform allows one-handed silencer installation and removal without tools or complex procedures. The mount features industry-standard 1.375-24 threads for compatibility with most current production silencers, making it a versatile addition to any suppressed rifle setup. We stock this alongside our full selection of suppressor adapters and mounting solutions.
Machined from 17-4 H900 stainless steel with a black nitride finish, this mount is built for hard use and corrosion resistance. The internal thread geometry provides solid, wiggle-free engagement with 51T muzzle devices, eliminating the accuracy-robbing play found in lesser mounting systems. A coil-spring tensioned pawl with textured thumb pad delivers secondary retention, ensuring your suppressor stays locked until you intentionally release it. The pawl axis pin is easily removable for field maintenance and cleaning. At just 1.77 inches overall length and 4.07 ounces, the mount adds minimal weight and length to your host firearm. Browse our suppressor mount collection for additional quick-detach options.
This mount shines for shooters who swap suppressors between multiple host rifles equipped with 51T muzzle devices.

Note that this mount is not compatible with the newer style 51T mounting systems. For shooters building out a suppressed rifle platform, we also carry a full range of muzzle brakes and flash hiders designed for suppressor-ready configurations.

Yes. The Spring Tensioned Accessory Mounting Platform design enables true one-handed operation. The textured thumb pad on the spring-tensioned pawl allows you to release the suppressor quickly while maintaining control of your firearm with your support hand.
Direct-thread suppressors screw directly onto barrel threads, requiring two hands and more time to install. The 51T S.T.A.M.P. mount uses a quick-detach system that locks onto compatible muzzle devices, allowing faster transitions and the ability to share one suppressor across multiple hosts.
This mount is compatible with legacy and current production 51 Tooth muzzle devices manufactured to Advanced Armament Corp specifications. However, it will not work with the newer style 51T mounting systems. Verify your muzzle device compatibility before purchasing.
