Smith and Wesson M&P15 Sport III Features The M&P15 Sport III runs on a mid-length gas system paired with a 1-in-8 R5 twist rate delivering reliable cycling and consistent accuracy across a wide range of 5.56 NATO and .223 Rem loads. The 16 inch barrel is threaded 1/2x28 for muzzle device or suppressor compatibility and the free-floating 15 inch M-LOK rail gives shooters extensive real estate for lights grips and other accessories without contacting the barrel. A 2-position thumb safety and integral trigger guard round out a control layout built for straightforward reliable operation. For shooters who want to add a suppressor or muzzle device without gunsmithing the threaded barrel delivers that compatibility out of the box. Built on a 7075 aluminum receiver finished in black hard coat anodizing the rifle holds up to repeated range use and field handling. The 6-position CAR collapsible stock adjusts the length of pull to fit different shooters and body armor configurations and the rifle feeds from an included 30-round PMAG for extended capacity. The complete package ships in a Tac-Six Engage tactical case along with Walker's Razor Slim ear muffs Walker's Clear Sport glasses and a Real Avid Gun Boss cleaning kit giving shooters everything needed for a day at the range. For shooters who want a complete rifle package with hearing and eye protection included the M&P15 Sport III's bundled gear rounds out a ready-to-shoot kit for sale at GrabAGun.
