Gen-2 Enhanced 16.6'' M-Lok Handgrd Free Float For Ar-15 Fde

The Aero Precision Gen-2 Enhanced 16.6'' M-Lok handguard in FDE is a free float rail system built for AR-15 rifles that want modularity, lightweight performance, and rock-solid stability. If you're building or upgrading a custom AR-15, this handguard replaces the factory tube with a one-piece design that isolates your barrel from the furniture, letting your gun shoot to its true potential while giving you M-Lok slots instead of traditional Picatinny for mounting optics, lights, and other gear exactly where you need them.

The Gen-2 Enhanced is purpose-built for real shooting. Anti-rotation tabs keep it locked in place, while scalloped rails and additional milling along the flats make it easier to grip and handle under recoil. The handguard features a continuous top rail for mounting optics or iron sights, and it's designed to work with most muzzle devices—including suppressors up to 1.5'' diameter—without getting in the way. Built to mil-spec dimensions and machined to tight tolerances, it delivers the strength and precision you'd expect from Aero's reputation.

Gen-2 improvements include quick-disconnect sling sockets at 3, 6, and 9 o'clock positions, a refined continuous top rail profile, and additional milling that improves grip texture and adds clean lines to your build. At 16.6 inches, this handguard strikes a balance between coverage and maneuverability, and it's lightweight enough that you'll actually notice the difference on long range days. Note: this model is specific to AR-15/M4E1 platforms and will not fit M5 .308 builds.

Frequently Asked Questions

Will this handguard fit my AR-15 build?

Yes, this is designed specifically for AR-15 and M4E1 platform builds. It will not work on M5 or .308 builds. If you're unsure about your upper receiver platform, check with us—we're happy to verify compatibility before you order.

Can I use a suppressor with this handguard?

Yes. The 1.78-inch inside diameter accommodates most muzzle devices and suppressors up to 1.5 inches in diameter, so you won't have clearance issues when running a suppressor at the range or afield.

What's different about the Gen-2 version?

The Gen-2 Enhanced adds quick-disconnect sling sockets at three positions (3, 6, and 9 o'clock), additional milling along the flats for improved grip purchase and appearance, and a refined profile for the continuous top rail. These refinements make it a more user-friendly and versatile upgrade to the original design.

Is this handguard low-profile gas block compatible?

Yes, it's engineered to work with low-profile gas blocks, so you can keep your top rail clean and unobstructed if that's your preference.
