The ArmaLite M-15 Defensive Sporting Rifle is a 5.56 NATO/.223 Remington carbine (ArmaLite part no. DEF15) built to provide shooters with a high-quality, scalable AR that’s easy to accessorize to any configuration. Light and strong at 6.1 lbs, it’s built around a forged flattop receiver with a MIL-STD 1913 rail and a 16-inch double-lapped, chrome-lined chrome moly barrel that’s both tough and dependable. The upper and lower receivers are forged from 7075-T6 aluminum with an anodized finish, and a railed gas block front sight base keeps the sighting system in reach without adding bulk. A 6-position collapsible stock and 6-inch handguard round out a compact, maneuverable package, and the rifle ships with a 30-round Magpul PMAG so it’s ready to run as soon as it arrives.
