Griffin Armament Low Pro Rigid M-Lok Rail

Griffin Armament Low-Pro-Rigid rails are a slim, low profile, ultralight, yet rigid M-Lok rail. Design objectives were to provide a slim, ultralight rail with increased rigidity over similar weight and profile current market options. A custom extrusion provides internal reinforcement to reduce flex when gripping the carbine firmly in the shoulder pocket. These reinforcements provide rigid mounting for IR laser aimers ensuring minimal POI shift when torque is applied to fore-grip type accessories, or when loads are applied to the rail. Internal testing showed 70% less POI shift with laser aimers versus competing slim rails. The rail features M-Lok slots at the 3, 6, and 9 o'clock positions. The heavy-duty 17-4 stainless steel H900 heat treated barrel nut is included, along with the Griffin Armorers wrench. The rail is easy to install.
