AeroPrecision
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.
