Gen-2 M5 (.308) 16.6'' Enhanced Mlok Free-Float Handguard Blk

Building a precision .308 AR platform means choosing components that won't compromise accuracy or durability. The Aero Precision Gen-2 M5 Enhanced M-LOK free-float handguard is purpose-built for serious M5 .308 builds—delivering lightweight modularity, rock-solid lockdown, and the kind of rail real estate that lets you configure your rifle exactly how you shoot it. At 16.6 inches, this handguard strikes a balance between coverage and handling, machined from 6061-T6 aluminum to exacting mil-spec tolerances and engineered to float freely above the barrel for consistent accuracy shot after shot.

The Enhanced M-LOK system gives you far more versatility than traditional Picatinny rails alone. You can mount lights, lasers, grips, and accessories wherever you need them without the weight penalty of solid aluminum. The Gen-2 updates add practical touches: quick-disconnect sling attachment points at 3, 6, and 9 o'clock, additional milling along the flat surfaces for a positive grip, and a refined continuous top rail profile. Built-in anti-rotation tabs ensure zero shift once you've locked it down on the barrel nut, while the scalloped rail design sheds unnecessary weight without sacrificing strength.

This handguard is built specifically for the M5 .308 and M5E1 platform—verify compatibility before ordering. It requires a separate barrel nut purchase and features a 1.72-inch inside diameter that accommodates most muzzle devices and 1.5-inch suppressors. The low-profile gas block compatible design keeps your setup running clean and efficient. Whether you're dialing in a long-range hunter, a precision competition rifle, or a tactical .308 build, this handguard gives you the foundation to add exactly the accessories your mission demands.
