The Geissele Super Modular Rail for the HK416 (brand part no. 05-190B) replaces the standard factory rail on HK416-platform rifles, measuring 10.5 inches and precision machined from 6061-T6 aluminum for strength, rigidity, and modularity. It utilizes the stock HK barrel nut, so there’s no need to swap that component, and it’s finished in Type 3 hardcoat anodize to meet military specifications. Rail sections at the 3, 6, and 9 o’clock positions use steel inserts for a solid, steel-to-steel connection when mounting accessory rails, making this the same rail system trusted by military units running the HK416 platform.
