Smith & Wesson M&P 15 Sport III Features The Smith & Wesson M&P 15 Sport III pairs a 16 4140 CM Armornite-finished barrel with a 1:8 twist 5R rifling profile that maximizes projectile contact for consistent accuracy and broad ammunition compatibility across the 5.56 NATO spectrum. A mid-length gas system reduces felt recoil for faster follow-up shots and more comfortable extended range sessions. The free-float M-LOK handguard opens the door to a wide range of aftermarket accessories without compromising barrel harmonics or accuracy. A forged integral trigger guard chromed firing pin forward assist and dust cover give this optics-ready 5.56 NATO AR rifle the reliability-focused details that Smith & Wesson M&P rifles are known for. The adjustable polymer stock and thumb safety deliver an intuitive customizable fit for shooters of any size or experience level. At 35 overall in a bold White finish with a single magazine included the M&P 15 Sport III is ready to run straight out of the box.
