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

15" Lightweight M-LOK Free-Float Handguard — DPMS / Aero .308 High Profile

The 15" Lightweight M-LOK Free-Float Handguard is engineered for builders looking to reduce weight while maintaining rigidity and compatibility on large-frame AR platforms. Designed specifically for aftermarket DPMS and Aero .308 high-profile uppers, this handguard delivers a clean, modern mounting solution for precision and general-purpose AR-10 builds.

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

CNC machined from quality aluminum and finished with a durable black anodized coating, this handguard provides strength without unnecessary bulk. The slim profile includes a full-length Picatinny top rail for optics and sights, along with M-LOK slots for flexible accessory mounting. At only 15 oz including the steel barrel nut, it offers excellent weight savings for large-frame builds.

Installation is straightforward with the included steel barrel nut and mounting hardware, making this rail a solid choice for builders seeking an affordable, lightweight free-float solution for compatible .308 platforms.
