The M&P15-22 rifle is a dedicated M&P15-format rifle designed and built as a true .22 LR semi-auto from the ground up, with all the standard operating features and accessory specifications of a modern version centrefire M&P15 rifle.  The rifle is built with high strength polymer upper and lower receivers, which creates a reduced weight rifle that retains the looks and operating features of the standard M&P rifle.  Some of the most popular versions that we retail are shown below.
