Battle Arms Development Workhorse 15" M-LOK Rail – AR-15 Platform

The Battle Arms Development Workhorse 15" M-LOK Rail delivers a lightweight, rigid mounting platform for AR-15 pattern rifles. Its full-length top rail and continuous M-LOK slots at 3, 6, and 9 o'clock positions provide versatile accessory placement for optics, lights, grips, and bipods without unnecessary bulk. The free-float design isolates the barrel from external pressure, supporting consistent accuracy across extended strings of fire.

Machined from 6061-T6 aluminum with a Type III hard-coat anodized black finish, this handguard installs via a standard barrel nut system (included) and fits low-profile gas blocks. The 15-inch length offers full coverage for mid-length and most carbine-length gas systems while allowing clearance for muzzle devices and suppressors. Anti-rotation tabs and steel hardware ensure a secure lockup to the upper receiver.
