Smith & Wesson M&P15 .300 AAC Blackout Features The USED / DEMO M&P15 in .300 Blackout is built to deliver flexibility and reliability on a proven AR platform. Its 16-inch Armornite-treated barrel provides enhanced corrosion resistance while the 5R rifling improves bullet stability and reduces fouling. The 1:7.5 twist rate is ideal for stabilizing a wide range of projectiles including heavy subsonic loads when paired with a suppressor. The barrel is threaded 5/8x24 making it suppressor- and muzzle device-ready out of the box. The rifle features a forged receiver with an integral trigger guard for strength and long-lasting durability. A gas block with an integral Picatinny-style rail allows for the mounting of front sights or optics offering flexibility in sighting systems. A chromed firing pin further enhances reliability under high round counts ensuring consistent ignition and reduced wear. Compatible with most standard AR-15 components and accessories this USED / DEMO M&P15 is easily customizable for a variety of shooting needs. Whether set up for hunting tactical shooting or suppressed fire the combination of quality construction and .300 AAC Blackout chambering makes this rifle a highly versatile choice.
