On the S&W M&P 15-22, a standard manual of arms reload is maintained; last shot bolt holds open, drop the mag, insert new mag, and hit the bolt release with the thumb. If you want to train for reloads, then the S&W currently is the only .22LR AR option.n a rimfire AR-15 such as the $500 street priced S&W M&P 15-22, it only takes 39 boxes of 50 .22LR or 1950 rounds and the gun has paid for itself. Obviously most ammo craze prices can make the break even point much faster. Just make sure your 25M zero is the same on both your 5.56 AR and your .22LR AR.
