Griffin Armament Low Profile RIGID™ M-LOK Rail Kit 10.5" / by RANGE R.A.T.S.

Griffin rail kits feature Low-Pro RIGID™ rails, 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 the included QD sling swivel 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.

M-LOK slots at the 3, 6, and 9 o'clock positions allow for mounting of the included Griffin RAIL SHIELD™ panels. The Included 4 piece RAIL SHIELD™ kit provides a 4.6" long surface on 3 sides of the rail for a full hand grip on the panels, ensuring that a hot rail from excessive firing does not burn the hand of the user. The angled geometry on the optional bottom piece is located as rearward as possible ensuring that torque can be applied to grip the rail while keeping the hand entirely on the RAIL SHIELD™ kit. The included Primo Gas Block™ provides a 416R crucible alloy low profile block that can be either set screwed in place easily by the user using the included cup point fasteners, or more securely installed by drilling the barrel and using the included and optional spline pin.
