Fortis Manufacturing REV II Free Float Rail - Ultra-Lightweight, M-LOK Compatible Handguard for AR-15

The Fortis Manufacturing REV II is a free float AR-15 handguard designed for shooters who refuse to compromise between weight and strength. Built on a single-piece construction, the REV II cuts unnecessary mass while maintaining the rigidity you need for accurate shooting—whether you're zeroing at the bench, running drills at the range, or hunting. It's the kind of gear that rewards you for every dollar spent by eliminating waste and keeping your rifle balanced where it matters.

The REV II mounts directly to a standard AR-15 barrel nut using Fortis's proven attachment system, making installation straightforward for anyone comfortable building or upgrading an AR. M-LOK slots at the 3, 6, and 9 o'clock positions give you genuine modularity without the weight penalty of over-engineered rail real estate—mount lights, grips, and accessories exactly where you need them. Anti-rotation tabs lock the handguard in place, so there's no shifting under recoil or during transitions.

Compatibility is broad: the REV II works with both direct impingement and piston-driven AR platforms, so your system choice doesn't limit your options. At 6.7 inches long with a 1.340-inch inside diameter, it's proportioned for standard AR uppers and offers enough rail space for optics, lights, and supports without turning your rifle into a quadpod.
