Geissele Automatics MK4 Federal M-LOK 10" Super Modular Rail

Featuring Type III anodized 7000 series aluminum construction, the Geissele Automatics® MK4 M-LOK® 10" Super Modular Rail is a combat-proven tactical rail system, designed to deliver superior strength, stability, and heat dissipation while simultaneously reducing the overall weight of your rifle for improved accuracy and control with your favorite AR-style rifle. Originally designed to fulfill contracts for the FBI, this rail features a proprietary 2.25” long barrel nut that helps increase the surface contact where the rail interfaces with your rifle’s receiver for a secure, wobble-free fit. This handguard comes equipped with multiple 1913 Picatinny rail sections at the 3, 6, and 9 o’clock positions along with Magpul® M-LOK accessory slots at the 3, 6, and 9 o’clock positions, maximizing your ability to accessorize and customize your rifle. Backed by a limited lifetime warranty. Compatible with mil-spec M4 upper receivers.
