The Smith & Wesson M&P15 Sport III (S&W part no. 14207) is a 5.56 NATO AR-15 that ships ready to shoot with a Crimson Trace CTS-106 red dot already mounted, saving buyers the cost and hassle of sourcing an optic separately. Smith & Wesson builds the Sport III with a 7075-T6 aluminum receiver, a 4140 steel barrel, and a mid-length gas system for smooth cycling. A full-length Picatinny rail runs the free-float M-Lok handguard, and the six-position adjustable stock lets shooters dial in their length of pull. This is a ready-to-go package for home defense, range use, or a first modern sporting rifle.
