Aero Precision Ar15 9.3" Enhanced M-Lok Handguard Gen 2 - Fde Apra100276C
Building a lightweight, modular AR15 starts with the right handguard. The Aero Precision 9.3" Enhanced M-LOK Handguard Gen 2 in FDE is a one-piece free-float design engineered for shooters who want precision without unnecessary weight. Whether you're assembling a dedicated precision rifle, a competition build, or a reliable duty gun, this handguard gives you the modularity of M-LOK attachment points combined with a continuous top rail for optic mounting and accessory flexibility—something older Picatinny-only designs simply can't match.
Machined to military specifications and built specifically for the AR15/M4E1 platform, this handguard uses Aero Precision's BAR (Barrel Address Reference) interface, which means superior concentricity and a rock-solid mounting surface. The one-piece construction eliminates flex and keeps your optics in zero. Inside diameter of 1.72" accommodates most common muzzle devices and runs suppressor-friendly at 1.5" diameter—no awkward fitment surprises. Low-profile gas block compatible, so you won't be fighting geometry during an upper assembly.
The Gen 2 revision adds meaningful improvements: quick-disconnect sling attachment points at 3, 6, and 9 o'clock positions give you carry options without bolting on adapters; additional milling on the flat surfaces provides positive hand placement and looks sharp; and a refined continuous top rail profile ensures smooth optic seating. Scalloped rail sections reduce weight further while the built-in anti-rotation tabs keep everything indexed and stable through hard use.
If you're running an M4E1 upper, you're ready to go—no barrel nut swap needed. Using a standard threaded upper? You'll need Aero's BAR Barrel Nut (sold separately). This is an AR15-specific part; it won't work on M5 .308 uppers. FDE finish pairs well with modern rifle builds and matches most contemporary combat-oriented platforms.

Frequently Asked Questions
Will this handguard work on my standard AR15 upper receiver?
Yes, but you'll need to use Aero Precision's BAR Barrel Nut, which is sold separately. If you're running an M4E1 Enhanced Upper Receiver, no additional parts are required—the handguard mounts directly. This handguard is not compatible with M5 .308 or M5E1 uppers.
Can I suppress my rifle with this handguard?
Absolutely. The 1.72" inside diameter accommodates most muzzle devices and 1.5" suppressors without fitment issues, making it suppressor-friendly for both range and field use.
What's the difference between Gen 2 and the original model?
The Gen 2 revision adds quick-disconnect sling attachment points at 3, 6, and 9 o'clock positions, additional milling on the grip flats for better hand placement and visual appeal, and a refined continuous top rail profile for smoother optic mounting.
Is this handguard compatible with my low-profile gas block?
Yes. This handguard is designed to work with low-profile gas block configurations without clearance issues during assembly and use.
