The ArmaLite DEF15 M-15 Defensive Sporting Rifle delivers classic AR-15 ergonomics in a streamlined, duty-ready configuration. Built on forged 7075-T6 aluminum upper and lower receivers with a flat-top MIL-STD 1913 rail, it pairs a 16" double-lapped, chrome-lined chrome moly vanadium barrel with a railed gas block and flash suppressor for dependable accuracy and smooth operation. The rifle ships with a Magpul PMAG and features a black synthetic 6-position collapsible stock and black polymer grip for familiar, comfortable handling.

Chambered in .223 Remington / 5.56 NATO with a 30+1 capacity, the M-15 Defensive Sporting Rifle is well suited for range use, training, and general sporting applications where reliability and straightforward performance matter. Its optic-ready receiver and gas block rail make it easy to configure with your preferred sights or accessories, while the lightweight 6.1 lb build keeps the rifle manageable over extended sessions.
