The BATTLEARMS® WORKHORSE™ series of firearms 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 matching Carpenter 158 steel bolt and 8620 black nitride carrier for ultimate reliability and ease of cleaning. 

In a class of its own, every WORKHORSE™ is outfitted with a new industry standard-setting RACK™ ambidextrous charging handle with monolithic handle and smooth side sliding latch that is built to take abuse.  Look a bit more closely and you will find this duty line of rifles are not so “plain jane”.  It is loaded with numerous enhanced components such as a smooth nickel Teflon trigger, enhanced magazine release, enhanced takedown/pivot pins for easy tool-less breakdown, one-piece magazine catch, billet trigger guard, enhanced bolt catch, user-adjustable three-position pistol grip, and enhanced single side safety

The WORKHORSE™ series offers an amazing value.  The perfect firearm for duty or home defense.
