Geissele Automatics MK4 Super Modular AR-15 M-LOK Handguard - Black - 10.5”

The Geissele MK4 Super Modular Rail is a rugged 10.5" AR-15 handguard designed for strength, modularity, and performance. Crafted from durable 7000 series aluminum with a Type 3 hardcoat anodized finish, it features integrated Picatinny rail sections at the 3, 6, and 9 o’clock positions for accessory mounting. The rail also includes M-LOK slots at the 3, 6, 9 o'clock and upper 45-degree angles, offering versatile attachment points. Its design includes extensive venting to help reduce weight and cool down your barrel during rapid firing. A key part of the MK4 is Geissele’s unique 2.25-inch barrel nut. This creates a very strong and secure link to your upper receiver, which helps create a rigid, accurate platform.
