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.

    Great, underrated rail

    Published by Stan M on 21st May 2023

    This rail is solidly built, and the build quality is impeccable. Barrel nut is great, and the rail lockup with the 4 torx screws and the tiny set screw is tight. I have no worries it will stay tight. More people should know about this rail.

    Amazing Products

    Published by Luis on 20th May 2023

    Been building a 300blk pdw for a while now and ha preplanned the look and size of everything needed. Handguard was the only thing that would be an issue as 8.5 inch handguards arent that common and of those out there not the toughest. Very happy to see Griffin had what i was after and now the finished product looks great. Already own an MK1 lower some BCG's, the meritime stock kits are on all my suppressed rifles. the 300blk my mk18 and a second 556 sbr. run the res22 on my 22lr firearms. Was a no brainer when i saw this handguard. easy to install. the internal ribs really make it feel like a robust system. didnt ready the part where the qd mount is not part of the bundle and bummed but still very recommended. never hesitate to purchase anything Griffin Armament. Keep up the awesome job!!!

    BEST M-LOK RAIL ON THE MARKET!

    Published by Shane Collins on 26th Jul 2019

    The length is perfect for my 9.5" .300BLK pistol build. This thing is reinforced on the inside, and SUPER rigid... but still lightweight and low profile. The rail is a sleeper... buy one.
