Gen2 M5 .308 15'' Enhanced Mlok Free-Float Handgrd Kodiak

The Aero Precision Gen2 M5 .308 15" Enhanced M-LOK free-float handguard delivers modularity and lightweight performance for precision .308 AR builds. Built for shooters who demand more mounting flexibility than traditional Picatinny rails alone, this handguard combines M-LOK slots with a clean, modern design—and Aero's Gen 2 refinements add quick-disconnect sling mounts and improved ergonomics that make it equally at home on a long-range rig or a tactical carbine.

Machined from 6061-T6 aluminum and engineered for the M5 .308 platform specifically, the 15" length strikes a balance between sight radius and modularity without the unnecessary bulk of older designs. The free-float design isolates the barrel from the handguard—a fundamental accuracy advantage—while anti-rotation tabs lock it firmly in place at the receiver. Inside diameter is 1.72" (forward of the barrel nut), accommodating standard muzzle devices and 1.5" suppressors, and it plays nicely with low-profile gas blocks if your build goes that route.

Gen 2 upgrades include quick-disconnect sling socket positions at 3, 6, and 9 o'clock, additional milling along the flats for better grip and visual appeal, and a refined continuous Picatinny top rail. The handguard ships without a barrel nut—you'll need to source that separately—but once mounted, you get a rock-solid platform for optics, lights, and accessories that won't shift under recoil or affect your zero.

This is an M5 .308 / M5E1–specific design; it will not fit AR15 or M4E1 platforms. Available in black or flat dark earth Cerakote, it's built to the tolerances serious shooters expect from Aero Precision.

No. This handguard is engineered specifically for the Aero Precision M5 .308 / M5E1 platform and is not compatible with AR15 or M4E1 receivers. Make sure you confirm your platform before ordering.

What barrel nut does it need?

The Gen2 M5 .308 handguard does not include a barrel nut and requires one to be purchased separately. Aero lists SKU 100-035-811 as the compatible option.

Can I run a suppressor with this handguard?

Yes. The 1.72" interior diameter accommodates most standard muzzle devices and suppressors up to 1.5" in diameter.

What's included in the box?
