M-LOK Free Float Slant Cut Quad Rail Handguard for AR-15

The M-LOK Free Float Slant Cut Quad Rail Handguard bridges the gap between traditional quad rails and modern M-LOK handguards. Designed as the perfect hybrid, it features Picatinny rail sections at the front for mounting lights, lasers, grips, and other accessories, while the center of the handguard transitions to M-LOK slots for reduced weight, a slimmer profile, and a more comfortable grip.

Unlike traditional free float handguards that require timing the barrel nut during installation, this handguard utilizes a secure clamp-on mounting system that eliminates barrel nut timing, making installation faster and easier. The lightweight 6061-T6 aluminum construction is finished with a durable Type II anodized coating for long-lasting performance and corrosion resistance.

Whether you're building a duty rifle, range gun, or custom AR-15, this hybrid rail system delivers the versatility of Picatinny where you need it most while taking advantage of the lightweight benefits of M-LOK.
