Gen-2 M5 (.308) 15'' Enhanced M-Lok Free-Float Handguard Fde

The Aero Precision Gen-2 M5 Enhanced M-Lok Free-Float Handguard in 15\" FDE is engineered for .308 AR platform builders who demand modularity, lightweight handling, and rock-solid stability without compromise. This handguard uses a true free-float design that isolates the barrel from contact with the hand guard, eliminating harmonics that can affect shot consistency—a critical feature for precision rifle builds. Built from 6061-T6 aluminum and machined to mil-spec tolerances, it delivers the strength you need while keeping weight down where it counts.

The M-Lok accessory mounting system gives you advanced modularity beyond traditional 1913 Picatinny rails, letting you attach lights, bipods, slings, and other gear exactly where you want them. The handguard ships with built-in anti-rotation tabs to keep it locked in place on the barrel extension, and includes quick-disconnect sling attachment points at the 3, 6, and 9 o'clock positions—a Gen 2 addition that makes field adjustments intuitive. Scalloped rails reduce weight and heat signature, while the 1.72\" inside diameter accommodates most muzzle devices and suppressor sizes up to 1.5". The additional milling along the flats adds ergonomic gripping surfaces and visual appeal without sacrificing rigidity.

This handguard is purpose-built for the M5 and M5E1 .308 platforms and will not fit AR15/M4E1 rifles. The barrel nut is sold separately, so verify you have the compatible DPMS High Profile (.210) Tang nut before installation. If you're running a low-profile gas block, this handguard was designed to work with that setup. Flat Dark Earth Cerakote finish resists corrosion and blends with modern tactical builds.
