Aero Precision M5 Enhanced Ar-10 M-Lok Handguard Gen 2 15" Black Apra308232

The Aero Precision M5 Enhanced AR-10 M-LOK Handguard Gen 2 is a lightweight free-float rail system built for serious .308 builds on the M5 platform. If you're customizing an M5 or M5E1 rifle and want modularity beyond traditional Picatinny, this 15-inch handguard delivers the kind of clean, minimal design that lets your optics and support gear take center stage while keeping the overall package nimble and rigid where it counts.

Built from 6061-T6 aluminum and machined to mil-spec tolerances, the handguard uses a free-float design with anti-rotation tabs to eliminate contact with the barrel—the gold standard for consistent accuracy. The M-LOK mounting system gives you flexibility to position accessories exactly where you need them, and the scalloped rail sections reduce weight without sacrificing strength. The 1.72-inch interior diameter accommodates most muzzle devices and 1.5-inch suppressors, and the design plays well with low-profile gas blocks so you're not locked into oversize setups.

The Gen 2 update brings three quick-disconnect sling socket positions (3, 6, and 9 o'clock) for hands-on versatility, additional milling along the flats for improved grip texture, and a refined top rail profile that looks as good as it handles. A continuous Picatinny rail up top gives you a rock-solid mount for your optic or backup sight. Note that the barrel nut is not included and must be purchased separately (Aero part SKU 100-035-811)—a common design choice that lets you select the nut that fits your build.

This handguard is purpose-built for the M5 .308/M5E1 platform and is not compatible with AR-15 or M4E1 rifles.
