Geissele Super Modular Rail MK4 10.5" M-LOK Handguard Black

The Geissele Super Modular Rail MK4 is a 10.5-inch free-float handguard for AR-15 rifles, built around an M-LOK attachment system for mounting accessories such as lights, grips and bipods. It is designed for shooters who want a lightweight, modular forend that can be configured to their needs.

The rail is machined from aluminum with a black hardcoat anodized finish. Its maximum venting reduces overall weight while keeping a rigid platform. Integrated M1913 Picatinny rail sections at the 3, 6 and 9 o'clock positions at the fore of the rail accept standard Picatinny accessories, and Magpul M-LOK slots are provided at the 3, 6 and 9 o'clock positions and the upper 45-degree quadrants.

The handguard mounts to the receiver with a proprietary 2-inch barrel nut, which increases contact surface with the receiver to help keep the rail straight and true along its full length and support repeatable zero after disassembly and reassembly.
