About the Smith & Wesson M&P15
The Smith & Wesson M&P15 is the company's direct-impingement carbine built on the standard AR-15 pattern, typically pairing a 16-inch barrel with a six-position collapsible stock. It arrived during the post-2008 expansion and became one of the first widely stocked ARs in big-box retail. Barrels commonly run a 1:9 twist, which stabilizes the 55- to 62-grain practice ammunition most owners shoot. Depending on the year, the rifle ships with a carry handle or a flat-top rail, and it accepts any standard AR accessory. It is a value-oriented entry that still holds mil-spec dimensions.
