Griffin Low-Pro RIGID rails are a slim, low profile, ultralight, yet rigid M-LOK rail. 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 70% 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 lightweight 7075 T6 Aluminum barrel nut, which can be installed with any car stock wrench or by using the included Griffin Armorers Wrench. Included shims allow barrel nut timing and keep the rear section of the rail low profile and ergonomically pleasing for relaxed posture carry at static positions. The included 17-4 stainless steel anti rotation QD sling swivel sockets install through the rail using a standard QD Sling Swivel (not included) and into the nut, ensuring that the rail is kept as low-profile as possible. In the same way, flat socket head cap screws are used in keeping with the sleek design objectives.
