The Battle Arms Development Workhorse series of firearms are built for duty and hard use. It is purpose-built around the forged BAD-15 7075-T6 aircraft-grade aluminum receiver and free-float rail handguard with M-LOK attachment point at 3, 6, and 9 o'clock positions. At 12 o'clock is a full-length Picatinny accessory rail with the signature notch cut matching the upper receiver. Every firearm is equipped with a 4150 chrome-moly steel black nitride barrel for durability and accuracy.
