About the Smith & Wesson M&P15 Sport II

The Smith & Wesson M&P15 Sport II launched in 2015 as the price-leader update to the original M&P15 Sport, with a forward assist, dust cover, and chrome-lined barrel — all features the original Sport lacked. At sub-$800 MSRP, the Sport II became the most-purchased AR-15 in America, particularly for first-time AR buyers. The Magpul edition (with MOE handguard and MBUS sights) adds furniture upgrades without raising the price meaningfully.
