Griffin Armament® Low-Pro 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 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.

Rail is somewhat slabsided and taller on the sides which gives it a good shape and fits in the hand comfortably. Barrel nut and lockup seems fine. No anti-rotation tabs that interface with the receiver (which is a plus if you are using a non-milspec or billet upper), but there is an allen screw that provides tension on the barrel nut for anti-rotation purposes. Inclusion of all tools necessary is a nice touch. Rail was packaged well in a box with convoluted foam. No instructions came with mine - pretty obvious to install, but I would have appreciated a torque reference for the torx screws+barrel nut. The specs are listed here on the website. Fits perfect with an 8.3 inch barrel, maybe 1/8-1/4" to the shoulder of the threads (5/8-24)
