The Rugged Suppressors Razor556 in FDE is a dedicated 5.56 NATO suppressor built for the AR-15 and M-16 (Rugged part no. RZRFDE556). It cuts blowback, recoil and flash while weighing only 13.4 ounces. A Cobalt 6 baffle core sits inside a 17-4 PH stainless steel tube, and a monolithic stainless mount attaches through the Quick Detach Dual Taper Locking System. Rugged rates it Belt Fed Rated with no barrel length restrictions. An SBR or full-size carbine can use it equally.
