Griffin Armament® M-LOK compatible SR-RIGID™ rails (Suppressor Ready - Rigid) allow up to 1.5” outside diameter silencers to be mounted inside the octagonal M-LOK rail. This provides suppressor aficionados a sleek, and compact overall length to AR15 type firearms.

Design objectives of this rail were to provide a suppressor compatible rail, with increased rigidity and durability over similar weight and profile current market options. A custom extrusion provides significant internal reinforcements to reduce flex when loading the carbine on the rail.
