The Super Modular Rail HK416 MK15 MLOK 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 MK15 meets military specifications.
Featuring MLOK mounting options at the 3, 6 and 9 o-clock positions, as well as featuring a full picatinny rail along the top and shortened picatinny rails on the forend. The Geissele SMR HK416 MK15 is trusted by our Nation’s elite warfighters, and their input was taken into consideration while developing the feature and performance rich SMR HK416 MK15.
