AAC 556-SD

Advanced Armament Corporation’s 556-SD can is a fast-attach silencer for your 5.56mm host. A retooled unit based on its renowned AAC M4-2000 brethren, the compact (6.7”) and lightweight (18 ounces) 556-SD offers suppressor enthusiasts a versatile,

feature-rich option. This suppressor employs AAC’s innovative 51T Ratchet Mount fast-attach system, enabling shooters to easily add/remove the can from the gun. (Which, in turn, results in more time destroying targets!) Regarding durability, the 556-SD sports a baffle core constructed of strong Inconel 718, along with a stainless steel body. We triple-dog dare you to push this silencer to the limit.
