Gen2 M5 .308 16.6'' Enhanced Mlok Free-Float Handgrd Kodiak

The Aero Precision Gen2 M5 .308 16.6" Enhanced M-LOK free-float handguard is purpose-built for serious .308 AR platform shooters who demand modularity, strength, and a lightweight profile. This handguard ships without a barrel nut (sold separately), so you'll need to source that component—but the free-float design itself eliminates the bulk of traditional furniture while maintaining the rigidity your precision rifle needs. The M-LOK mounting system gives you far more customization options than older Picatinny rail-only designs, letting you attach accessories exactly where you need them without rail clutter.

The Gen2 improvements over earlier iterations show Aero's attention to shooter feedback: quick-disconnect sling attachment points at the 3, 6, and 9 o'clock positions let you run your rifle how you want, while additional milling along the flat surfaces improves grip texture and gives the handguard a more refined look. Inside, the 1.72" diameter accommodates most common muzzle devices and 1.5" suppressors, and it's compatible with low-profile gas blocks so you can build a compact, efficient setup. The continuous top Picatinny rail gives you a traditional optics mounting platform without sacrificing the modularity M-LOK provides elsewhere.

Machined from 6061-T6 aluminum with mil-spec tolerances, this is a genuinely free-float design—the barrel doesn't contact the handguard, which is exactly what you want for accuracy and consistency. The anti-rotation tabs keep everything in place during installation and heavy use. This handguard is specific to the M5 .308/M5E1 platform and will not fit AR15 or M4E1 rifles, so confirm your receiver before ordering.
