Geissele Automatics Super Modular Rail HK

The Geissele Super Modular HK 416 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. 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 elite warfighters, whose direct input and feedback allowed Geissele to develop the feature and performance rich SMR 416. 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.
