Spike's Tactical Combat Rated Rail has been completely reengineered with improved function, durability, and looks. The newly designed rail has two anti-rotation tabs that keep the rail where you want it, and the kit comes complete with all components needed for easy installation.

Improved Shooting Experience

The new Spike's Tactical M-LOK handguard is designed with free-float ergonomic features and a reinforced QD sling swivel slot on both sides of the rail to make your firearm easy to carry, mount, hold, and shoot. The free-floating design and M-LOK mounting slots at the three-, six- and nine-O'clock positions provide ultimate flexibility for mounting a wide variety of accessories, and the rail compliments billeted AR uppers and lowers.

High-Quality Material

Spike's Tactical Combat Rated Rail is precision machined from a single piece of durable 6061-T6 high strength aluminum. The fluted body significantly reduces the rail's weight, and its narrow 1.8-inch diameter profile is designed to make the rail compatible with a wide array of muzzle devices. In addition, the rail has a Mil-Spec Type III hardcoat black anodized finish and is backed by a lifetime warranty.

No-Hassle Installation

Spike's Tactical M-LOK handguard is a snap to install and offers you four optional mounting locations. The installation kit comes complete with shims and a barrel nut that is compatible with standard three-pin barrel nut wrenches.
