The Geissele 14.5" HK416 M-LOK MK15 Black Super Modular Rail 05-826B was designed to replace the standard rail on an HK416 or MR556 weapon platform. The rail system utilizes the stock HK barrel nut, incorporating the strength and rigidity expected of a Geissele product.

This Geissele MK15 is made from 6061-T6 aluminum and finished in Type III hardcoat anodize, meeting military specifications. M-LOK mounting options sit at the 3, 6, and 9 o'clock positions along the rail's full length, backed by a full Picatinny rail along the top and shortened Picatinny sections on the forend.

Trusted by our Nation's elite warfighters, this Geissele HK416 handguard had its feature set shaped directly by operator input during development. This Geissele Super Modular Rail carries a 1.35" inner diameter and 2.08" outer diameter at a height of 2.61", optimized specifically for a 14.5" barrel. Weight comes in at 14.2 oz, keeping the front end manageable at this length.
