Sharps Bros AR-15 M-LOK Full Top Rail Handguard - Aluminum Black

The Sharps Bros AR-15 M-LOK Full Top Rail Handguard delivers a modern modular platform for shooters who want flexibility without unnecessary bulk. This 15-inch aluminum handguard combines a full-length top rail with M-LOK mounting slots across seven additional sides, letting you configure optics, lights, and accessories exactly where you need them. Whether you're building a precision rifle, a tactical carbine, or a general-purpose AR, this rail system adapts to your setup while keeping weight down where it matters.

Built from 6061-T6 aluminum and finished in mil-spec anodized black (MIL-A-8625F, TYPE III, CLASS 2), the handguard is tough enough for hard use in the field. The included anti-rotation tabs lock the rail securely to your upper receiver, eliminating unwanted movement during shooting or equipment changes. Installation is straightforward thanks to the included barrel nut and hardware—everything you need to mount it on most standard AR-15 platforms ships in the box.

At 10 ounces, the handguard keeps your rifle's balance and handling nimble, and the full top rail gives you prime real estate for mounting a scope, red dot, or night vision without compromising M-LOK access elsewhere on the rail. If you're tired of handguards that force you to choose between a top rail and side modularity, this system gives you both. The combination of proven mil-spec construction and thoughtful ergonomic design makes it a trusted choice for hunters, 3-gun competitors, and carbine enthusiasts looking to upgrade or troubleshoot a rifle platform.
