Smith & Wesson has expanded its Military & Police (M&P) Rifle Series with the introduction of a new tactical rifle chambered in .22 LR: the M&P15-22. Engineered with a high-strength polymer upper and lower receiver, the M&P15-22 benefits from reduced weight while retaining the looks and operating features of the standard M&P15 rifle. A six-position collapsible stock accommodates a variety of shooters and shooting positions. The A3 style flat top upper receiver with a quad-rail handguard allows for easily mounting optional accessories and the A2 pistol grip allows for improved firearm control. Fully functional charging handle, an AR-15 style magazine release, bolt catch, and a two-position, receiver-mounted safety. Includes a removable 25-round magazine, a removable A2-style front post sight, an adjustable A2-style rear sight, and a single stage trigger. The high-strength polymer magazine holds 25 rounds of ammunition.
