Griffin Armament® M-LOK compatible LOW-PRO-RIGID™ rails have been re-engineered to offer a user friendly installation while continuing to provide a slim, low profile, ultralight, yet rigid handguard that past users have loved.

Design objectives of this rail were to provide a slim, ultralight rail, with increased rigidity and durability 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.

Evan Green, Business Manager, of Griffin Armament states, “We understanding the importance of low light targeting with IR lasers. Reducing flex with our ID reinforcement spars reduces POI shift related to rail mounted lasers. These rails offer more accuracy (less flex) than their competition which means more lethality under hours of darkness.”

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 such as practical shooting off barricades or when loading bipods for rapid follow up shots. Internal practical testing showed 70% less POI shift with laser aimers versus competing "slim rails" that lacked this notable product feature.

The new LOW-PRO-RIGID™ rail features a close tolerance, heavy-duty, 17-4 stainless steel H900 heat treated barrel nut, which can be easily installed to the specified 55 ft/lbs with the included Griffin Armorers Wrench. The new slip fit clamp design is extremely user friendly and does not require any shims or special timing methods. The clamp geometry in the rear section of the rail is low profile and ergonomically pleasing even for long durations of extended carry at static security positions. Flat head T15 torx screws should be tightened to 25/in pounds. The included 45 degree picatinny QD sling swivel can be installed on the top picatinny rail to the desired position of the end user. M-LOK slots at the 3, 6, and 9 o'clock positions allow for mounting of your favorite M-LOK accessories.

If you are looking for a high quality, feature rich, American made rail system for your AR15 type firearm look no further than Griffin Armament® LOW-PRO-RIGID™ rails!
