Geissele Automatics 05-854B M-LOK HK416 Rail

The Super Modular Rail HK416 M-LOK was designed to replace the standard rail on an HK416 or MR556 weapon platform. The rail system utilizes the stock HK barrel nut, but incorporates the strength, rigidity and modularity expected of a Geissele product. Made from 6061-T6 aluminum and finished in type 3 hardcoat anodize, the SMR HK416 M-LOK meets military specifications. Featuring M-LOK mounting options at the 3, 6 and 9 o'clock positions the entire length of the rail, as well as a full picatinny rail along the top. Geissele Super Modular Rails are trusted by our elite warfighters, and their input was taken into consideration while developing the feature and performance rich SMR HK416 M-LOK series of handgaurds. Disclaimer: If the HK upper receiver group has sling loops on the outside of the gas block they will need to be removed for installation. This is a permanent modification. It is recommended this procedure be done by a certified and professional gunsmith/armorer.
