Battle Arms Development Workhorse 13-inch M-LOK Handguard Black

The Workhorse M-LOK compatible rail system from Battle Arms Development is a lightweight, slimline free-float handguard designed for use on Mil-Spec AR-15 carbines. It provides M-LOK attachment points at the 3, 6, and 9 o’clock positions and a notch-cut 1913 Picatinny rail at 12 o’clock to align with compatible upper receivers while reducing weight. Skeletonized sections where M-LOK is not used help trim mass without sacrificing functionality. Offered in a 13-inch length to suit a range of barrel and build requirements.
