Description

The Geissele Super Modular Rail MK4 M-LOK is a free-float handguard for AR-15 rifles, built from aluminum in a black finish. It uses M-LOK attachment slots at the 3, 6 and 9 o'clock positions and the upper 45-degree quadrants, and integrated M1913 Picatinny rail sections at the fore of the rail at 3, 6 and 9 o'clock.

The rail is 9.3 inches long and attaches with a barrel nut. Maximum venting is used to reduce weight while keeping the platform rigid. Geissele's proprietary 2-inch-long barrel nut increases surface contact with the receiver to help the rail stay straight along its full length and support zero repeatability during disassembly and reassembly.

The handguard is chambered for the 223 Remington and 5.56x45mm NATO cartridges, which are the calibers listed for this platform.
