Griffin Armament Low Pro Rigid M-LOK Rail
Griffin Armament 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 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.

Amazing
Easy to install. Super light yet rigid. Went on duty rifle and performs exactly how it should. Definitely need a low pro gas block tho.
GURail

USSlim hand guard
Perfect to finish out my griffin armament 11.5” build.

****** expensive but it does come with extras and it's a super nice rail
First off this is the kit that comes with the rail, the handstop and mlok panels, gas block, a single qd swivel, a small armorer's wrench and all the hardware you'll need (mostly.) Unfortunately it doesn't come with instructions but it's pretty straightforward. The only thing I'll say is when you tighten the barrel nut be sure to use the deeper slots or it will slip off and damage the barrel nut. Ask me how I know. Fit and finish are top notch as I expected with it being a Griffin Armament product. Mine was missing a single screw that attaches the rail to the barrel nut but an email to Griffin Armament and it was shipped off to me free of charge that same day. I have several of their products with plans to buy more and their customer service is just one reason why. The rail feels good in the hand and the panels make it just the perfect size for me personally to grip it when shooting. I have to mount my 45 offset re dot on the rail right where the barrel nut is due to space and I didn't notice any poa poi shifts after shooting a few mags either which is nice. Now I just have to wait for the scope mount I want and RMR plate to come back in stock so I can get my 45 off the rail.
USNice product. Manufacturer's packaging could be better.
The handguard slipped out of the open-ended plastic sleeve it was in and got a little banged up against other parts inside the manufacturer's box. Dings were minor, but some were enough to create edges sharp enough to catch a cloth. Still seems like a very high quality product. Be advised, there is no anti-rotation feature. The manufacturer states it is not necessary since it would take ridiculous amount of force to rotate the handguard on the barrel nut, but this doesn't address the nut itself lacking a locking feature. I doubt it's an issue, but the original design uses the gas tube for this. If that bothers you, the design of the BCM MCMR addresses this and is an excellent product. That one is my favorite, but this handguard came in a better length for this project.
