The Griffin Armament M4SD-L is a lightweight 5.56 NATO suppressor built with Griffin's laser-welded tubeless construction. Leaving out the traditional outer tube saves weight, and the 17-4 H900 heat-treated stainless steel is welded into a single unit Griffin says matches the durability of tube-over designs. The suppressor body is Cerakoted, and Griffin covers it with a perpetual lifetime warranty.

The GATE-LOK QD mount is one of the fastest on the market and fits Griffin GATE-LOK devices as well as mil-spec A2 NATO compensators; a GATE-LOK Hammer Comp (1/2x28, .22 cal) is included. Griffin's ECO-FLOW baffles let gas flow through to reduce blowback on semi-auto and full-auto hosts, and the Pressure Reduction Cap adds flash reduction and tuned venting. This is an NFA item.
