The 51T S.T.A.M.P Mount™ from Advanced Armament Corporation represents the pinnacle of accessory mounting systems, tailored for those who demand precision and reliability in their firearms. This innovative fast-attach system is meticulously engineered to be compatible with both legacy and current production 51 Tooth muzzle devices crafted to AAC's exacting standards. In a world where time is often of the essence, the S.T.A.M.P Mount™ allows users to swiftly attach or detach a silencer using just one hand. Its design leverages intuitive motion and gross motor skills, ensuring that even under pressure, operation remains fluid and efficient. The heart of this mount lies within its Spring Tensioned Accessory Mounting Platform—a sophisticated mechanism featuring an internal ACME thread alongside spring tensioned elements that guarantee secure engagement without any unwanted movement. To further enhance security, this mount incorporates a coil-spring tensioned toothed pawl equipped with a textured thumb pad for ease of use. Should wear occur over time on the pawl teeth—an inevitability in high-use scenarios—the axis pin facilitates straightforward replacement, maintaining operational integrity without hassle. Compatibility is key in today's diverse firearm landscape. The S.T.A.M.P Mount™ answers this call with industry-standard 1.375-24 threads, accommodating most modern silencers effortlessly while excluding compatibility with MITER style 51T systems. For those who value efficiency coupled with unwavering stability in their shooting experience, the AAC 51T S.T.A.M.P Mount™ stands as an indispensable tool—uniting innovation with practicality seamlessly.
