Smith & Wesson charged boldly into the AR-15 market with its introduction of the M&P15 series in the early 2000s, and these rifles quickly became some of the best sellers on the market. Smith & Wesson continues to introduce new and innovative models, and its latest is the M&P15 AXE pistol and short-barreled rifle chambered in .300 Blackout. The new M&P AXE pistols (pictured) and SBRs mark the first Smith & Wesson firearm to be offered in .300 Blackout. In 2025, Smith & Wesson introduced its AXE series. Other notable features of the AXE series include a flat-faced trigger and an enhanced bolt carrier group.
