17″ AR-10 M-LOK Free Float Handguard | DPMS & Aero .308 High Profile - Cerakote

17″ Lightweight M-LOK Free-Float Handguard — DPMS / Aero .308 High Profile

The 17″ Lightweight M-LOK Free-Float Handguard is engineered for builders seeking extended rail length, reduced weight, and reliable compatibility on large-frame AR platforms. Designed specifically for aftermarket DPMS and Aero .308 high-profile uppers, this handguard provides increased control and mounting space for precision and long-barrel AR-10 builds.

This is a true free-float rail system, attaching only at the barrel nut and eliminating contact with the barrel. By isolating the barrel from external pressure caused by grips, bipods, or accessories, the free-float design helps improve accuracy compared to traditional two-piece handguards that can flex against the barrel.

CNC machined from high-quality aluminum and finished in a durable black anodized coating, this handguard balances strength with weight savings. The extended 17″ length provides additional hand placement options and accessory space while maintaining a slim, ergonomic profile. A full-length Picatinny top rail supports optics and backup sights, while M-LOK slots allow for flexible, low-profile accessory mounting.

Installation is straightforward using the included steel barrel nut and mounting hardware, making this an excellent choice for builders looking for an affordable, lightweight, and accurate free-float solution for compatible .308 platforms.
