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

The Aero Precision Gen-2 Enhanced 16.6'' M-LOK handguard delivers a lightweight free-float setup purpose-built for AR-15 and M4E1 platform builds. If you're customizing your rifle and want to shed unnecessary weight without sacrificing rigidity, this one-piece design eliminates the bulk that comes with heavier fore-end systems while keeping your barrel centered for improved accuracy. The M-LOK mounting standard gives you far more modularity than older Picatinny-only setups—you can attach rails, lights, and other gear exactly where you need them, not where a rail happens to be.

Gen-2 refinements make this handguard more practical in the field and on the bench. Quick-disconnect sling attachment points at 3, 6, and 9 o'clock positions mean you can set up your rifle for your shooting style in seconds. The updated continuous top Picatinny rail plays nicely with optics and backup sights, while additional milling along the sides gives you real purchase when gripping the gun and adds visual character to your build. Built-in anti-rotation tabs lock the handguard to your upper receiver so there's zero wobble, and the internal diameter accommodates most common muzzle devices and smaller suppressors.

Aero Precision machines these to mil-spec tolerances, and the scalloped rail design keeps weight down without cutting into strength. If you're running a low-profile gas block—increasingly common on modern builds—this handguard clears it. Just note: this is engineered specifically for the AR-15/M4E1 platform and won't fit the larger M5 or M5E1 .308 receivers.

Frequently Asked Questions

Will this handguard fit my AR-15 upper receiver?

Yes, if you're running a standard AR-15 or M4E1 upper. This handguard is specifically engineered for those platforms. It will not work with the M5 or M5E1 .308 platform.

Can I attach a suppressor with this handguard?

The interior diameter is 1.78 inches, which fits most common muzzle devices and 1.5'' suppressors. Always verify your specific suppressor diameter to confirm clearance.

What mounting system does it use?

This handguard uses the M-LOK standard, which provides significantly more modularity than older Picatinny-only systems. You can attach M-LOK accessories directly to the handguard sides and bottom, and there's a continuous Picatinny rail on top for optics and backup sights.

Does this work with low-profile gas blocks?

Yes, the handguard is compatible with low-profile gas block configurations, which is increasingly common on modern AR builds.
