Aero Precision Ar15 12" Enhanced M-Lok Handguard Gen 2 - Fde Apra100284C

The Aero Precision AR15 12" Enhanced M-LOK Handguard Gen 2 in FDE is a purpose-built free-float rail system designed for shooters who want modularity, light weight, and rock-solid stability on their custom AR platform. If you're building or upgrading an AR15, this handguard replaces the traditional picatinny-only approach with M-LOK slots that let you mount accessories exactly where you need them—and remove what you don't. The one-piece free-float design isolates the barrel from the rest of the rifle, which means you get repeatable accuracy without interference from the furniture.

Gen 2 refinements make this handguard noticeably more user-friendly than its predecessor. The continuous top picatinny rail gives you a backup option for optics or accessories if you prefer traditional mounts, while quick-disconnect sling sockets at 3, 6, and 9 o'clock positions let you run a sling any way you want. The flats along the sides are milled to improve grip texture and give the handguard a more finished look. Inside, the 1.72" diameter accommodates most common muzzle devices and fits 1.5" suppressors, so you're not locked into a single setup. The built-in anti-rotation tabs and compatibility with low-profile gas blocks mean you can keep your build clean and balanced.

One important note: this handguard uses Aero Precision's BAR interface. If you're mounting it on a standard threaded upper receiver, you'll need the matching BAR Barrel Nut—it doesn't work with a standard AR nut. If your upper is an Aero M4E1 Enhanced, you're ready to go with no additional hardware. The handguard is AR15/M4E1 specific and not compatible with the M5 or M5E1 platforms.

Frequently Asked Questions

What barrel nut do I need for this handguard?

The Aero Precision AR15 Enhanced M-LOK Handguard uses the BAR interface. If you're installing it on a standard threaded upper receiver, you must use the matching BAR Barrel Nut—a standard AR nut will not work. If you have an Aero M4E1 Enhanced Upper Receiver, no additional barrel nut is required.

Will this work on my AR platform?

This handguard is designed for AR15 and M4E1 platforms. It is not compatible with the M5 or M5E1 (.308) platforms. Verify your upper receiver type before ordering.

What size suppressors and muzzle devices fit inside?

The interior diameter is 1.72" at the forward end and 1.78" at the barrel nut cut, which accommodates most standard muzzle devices and 1.5" suppressors. Your specific device may vary, so check the dimensions of your component.

Can I use this handguard with a gas block?

Yes, this handguard is compatible with low-profile gas blocks and is designed as a free-float system that isolates the barrel from the rail.
