Geissele Automatics Super Modular Rail MK15 10.5" M-LOK Handguard - HK416/MR556 - Black

The Geissele Automatics Super Modular Rail MK15 is a purpose-built free-float handguard engineered as a direct-replacement rail for HK416 and MR556 weapon platforms. Machined from 6061-T6 aircraft-grade aluminum and finished in Type III hardcoat anodize, this 10.5" rail is built to military specifications for rigidity, return-to-zero performance, and long-term durability.

The MK15 uses Geissele's proven Super Modular mounting interface and is designed to deliver an ultra-rigid optics platform without sacrificing the slim handling profile of the host firearm. M-LOK mounting slots are provided at the 3, 6, and 9 o'clock positions for accessories such as lights, lasers, and grips, while a full-length Picatinny rail runs across the 12 o'clock surface for red dots, magnifiers, and backup iron sights.

At 10.5", this is the compact offering in the MK15 lineup, ideally suited to shorter-barrel HK416 and MR556 builds. Every Geissele Super Modular Rail is engineered and manufactured to the same exacting tolerances that have made Geissele Automatics a trusted name among professional users and enthusiasts.
