The Smith & Wesson M&P15-22 Sport solves the issue of the need to train with their rifle but instead of shooting lower cost .22lr ammo through a drop in bolt conversion kit which can gum up your gas system and tend to have unreliable magazines. The S&W MP15-22 Sport is a standalone rifle designed from the ground up to fire .22lr, with magazines specifically designed to function in the rifle with a lighter weight spring and geometry to feed the rimfire ammo perfectly. Lightweight polymer receivers and MLOK rail keep the M&P15-22 under 5lbs so its perfect for new or younger shooters, and the light recoil of the .22lr is great for volume training. The MLOK handguard can be customized with sections of rail for mounting lights, lasers, vertical grips, or any other accessories to fit the shooters needs. The carbon steel barrel delivers excellent accuracy and the Armornite coating provides durability for years of service. Able to accept a variety of standard AR15 parts like stocks, grips, and triggers the Smith and Wesson M&P15-22 .22lr is an excellent choice for a rimfire AR-15. All Smith and Wesson firearms are covered by their lifetime service policy.
