The Smith & Wesson M&P15 LE 311003 is an optic-ready AR-style semi-automatic rifle chambered in .223 Remington/5.56 NATO with a 16-inch barrel and a 6-position collapsible stock. It uses forged 7075 T6 aluminum upper and lower receivers paired with a 4140 steel barrel finished in Black Armornite for durable, everyday handling. This model ships with a 30-round magazine and includes a forward bolt assist and dust cover for reliable operation. A Vortex Strike Eagle 1-6×24 is a practical optic under $1000 that pairs well with this platform for both close-to-midsize engagements.
