Aero Precision Ar15 9.3" Enhanced M-Lok Handguard Gen 2 - Black Apra100275C
The Aero Precision AR15 9.3" Enhanced M-Lok Handguard Gen 2 is a free-float option built for shooters who want modularity, weight savings, and rock-solid stability on their custom AR15 build. M-Lok slots replace traditional Picatinny rail across the handguard, letting you mount accessories exactly where you need them without the bulk of full-length quad rail. This Gen 2 iteration refines an already proven design with improved ergonomics and a new top rail profile that keeps your sight picture uncluttered while staying quick to configure.
Built to mil-spec dimensions and machined for a precision fit, the one-piece free-float design isolates your barrel from the handguard, which pays dividends in accuracy and repeatability—especially important if you're stretching shots at distance or demand consistency from range to field. The scalloped M-Lok rails keep weight down without sacrificing mounting real estate, and the continuous top Picatinny rail gives you a traditional reference if you're running a scope or red dot. Interior diameter of 1.72" accommodates most muzzle devices and 1.5" suppressors, and the design plays nice with low-profile gas blocks so you're not forced into oversized or incompatible components.
Gen 2 refinements include quick-disconnect sling attachment points at 3, 6, and 9 o'clock positions, additional milling along the flats for better grip purchase and visual interest, and that updated top rail. One important note: if you're installing this on a standard threaded upper receiver, you'll need Aero Precision's BAR Barrel Nut—handguards with the BAR interface don't work with conventional barrel nuts. If you're running an M4E1 Enhanced Upper, you're good to go as-is. This handguard is AR15/M4E1-specific and won't fit the larger M5/.308 platform.

Frequently Asked Questions
Will this handguard work on my AR upper with a standard barrel nut?
No. The Enhanced M-Lok Handguard Gen 2 uses the BAR interface and requires Aero Precision's BAR Barrel Nut for installation on a standard threaded upper receiver. If you're running an Aero Precision M4E1 Enhanced Upper Receiver, you won't need any additional hardware—the handguard installs directly.
Is this compatible with my M5 or .308 AR?
No. This handguard is designed exclusively for the AR15/M4E1 platform and is not compatible with the larger M5, M5E1, or .308 platform receivers.
Can I run a suppressor under this handguard?
Yes, the 1.72" interior diameter supports most muzzle devices and 1.5" suppressors. Make sure your specific suppressor fits within the bore diameter before purchase.
What's the difference between Gen 2 and the original Enhanced M-Lok Handguard?
Gen 2 adds quick-disconnect sling sockets at the 3, 6, and 9 o'clock positions, features additional milling along the flats for improved grip, and includes a refined top Picatinny rail profile compared to the original design.
