The Battle Arms Development Workhorse series of AR-15 pistols are built for duty and hard use in mind. 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 our signature notch cut matching the upper receiver. Every firearm is equipped with a 4150 chrome-moly steel black nitride barrel for durability and accuracy. Each barrel is individually head-spaced with a matching 9310 steel bolt and 8620 black nitride carrier for ultimate reliability and ease of cleaning.
