Geissele Super Modular Rail MK4 M-LOK 15" Handguard Black

The Geissele Super Modular Rail MK4 M-LOK is a 15-inch free-float handguard for the AR-15 platform, designed for shooters who want to mount accessories across the forend. It is built from 6061-T6 aluminum with a black anodized finish and features M-LOK attachment slots for modular accessory mounting.

The rail includes integrated M1913 Picatinny rail sections at the 3, 6, and 9 o'clock positions near the fore of the handguard, and M-LOK slots at the 3, 6, and 9 o'clock positions as well as the upper 45-degree quadrants. Maximum venting reduces overall weight while maintaining a rigid platform. The rail uses a proprietary 2-inch long barrel nut that increases surface contact with the receiver to help keep the free-float rail straight and aid repeatable zero during disassembly and reassembly.
