Battle Arms Development 9.5" Workhorse M-LOK Free-Float Handguard for AR Rifles - Black

The Battle Arms Development 9.5" Workhorse M-LOK free-float handguard is a lightweight, purpose-built rail system designed for AR rifles that need a balance of modularity and weight savings. Built from 6061 T6 aluminum with a Type 3 black hardcoat anodize finish, this handguard delivers the durability you'd expect from a field-proven design without the bloat of unnecessary material. The 9.5" length fits mid-length barrels and works across MIL-SPEC carbine platforms, making it a practical choice for shooters building a versatile rifle for the range, hunting, or tactical training.

What sets the Workhorse apart is its thoughtful engineering. M-LOK slots are positioned at the 3, 6, and 9 o'clock positions, giving you flexibility to mount lights, vertical grips, sling attachments, and other accessories exactly where you need them. Where M-LOK isn't required, the rail system features skeletonized areas—open cut-outs that shed ounces without sacrificing strength. The top rail is a full-length 1913 MIL-SPEC Picatinny, but Battle Arms didn't stop there; they notch-cut it to match their upper receiver and trim weight again. Every design choice serves a function.

Installation is straightforward: secure the barrel nut to 30-45 foot-pounds and M-LOK screws to 10-15 inch-pounds. The 1.36" internal diameter accommodates standard AR uppers. Whether you're assembling a lightweight patrol rifle, a precision carbine, or a hunting build, the Workhorse delivers functionality without excess—exactly what experienced builders expect from Battle Arms Development.
