The Geissele Automatics HK416 Super Modular Rail M-LOK was designed to replace the standard rail on an HK416 or MR556 weapon platform, utilizing the stock HK barrel nut while incorporating the strength, rigidity and modularity expected of a Geissele product. Crafted from 6061-T6 aluminum with Type 3 hardcoat anodizing, the Super Modular Rail is made to withstand rigorous conditions. At 10.5 inches in length and weighing 10.4 ounces, this handguard features a height of 2.61 inches.
The rail features 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. This configuration allows seamless customization with tactical accessories including lights, lasers, and foregrips while maintaining secure optics mounting. Made from 6061-T6 aluminum and finished in type 3 hardcoat anodize, the Super Modular Rail HK416 M-LOK meets military specifications.
Geissele Super Modular Rails are trusted by our Nation’s elite warfighters, and their input was taken into consideration while developing the feature and performance rich HK416 M-LOK series of handgaurds. The 10.5-inch black model delivers a slim, ergonomic platform that optimizes both form and function for tactical and sporting applications.
