From the manufacturer
Griffin Armament Low Pro Rigid M-Lok Rail 12.5in Black Large. Design objectives of this rail were to provide a slim ultralight rail with increased rigidity over similar weight and profile current market options. A custom extrusion provides significant internal reinforcement to reduce flex when gripping the carbine firmly in the shoulder pocket. Understanding the importance of low light targeting 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 (shooting off barricades loaded bipods etc). Internal testing showed 70percent less POI shift with laser aimers versus competing "slim rails". Carefully positioned slots in the rail allow for rapid cooling when running the carbine fast while maintaining rigidity. The Low-Pro-Rigid rail features a close tolerance heavy-duty 17-4 stainless steel H900 heat treated barrel nut which can be installed with the included Griffin GI Armorers Wrench. The rail is very user friendly to install. The slip fitted clamp design doesn't requiring any shims or special timing methods. The clamp boss in the rear section of the rail is low profile and ergonomically pleasing for relaxed posture carry at static positions. Flat head T15 torx screws should be tightened to 25/in pounds. The barrel nut should be tightened to 55ft/lbs. M-Lok slots at the 3 6 and 9 o'clock positions allow for mounting of your favorite M-Lok accessories.
