Geissele 10.5 in. HK Super Modular Rail

The Geissele 10.5 in. HK Super Modular Rail was designed to replace the standard rail on the HK 416 weapon platform. Constructed of precision machined, 6061-T6 aluminum allows the SMR HK to incorporate strength, rigidity and modularity while utilizing the stock HK barrel nut. The Geissele 10.5 in. HK Super Modular Rail is finished in Type 3 Hardcoat Anodize to meet military specifications and able to use rail sections at the 3, 6 and 9 o’clock positions to mount accessory rails, using steel inserts for a rock solid, steel to steel connection; the SMR HK is trusted by our Nation’s elite warfighters, whose direct input and feedback allowed us to develop the feature and performance rich SMR 416.

Please note SMR HK rails do not come with accessory rail sections.
