With the ever increasing cost of 5.56mm and .223 ammo, Smith & Wesson is pleased to announce the M&P15R Rifle (along with the new Upper Receiver Assembly). This new rifle is chambered for the less expensive and abundant 5.45 x 39mm cartridge. The rifles come with a flat-top receiver and the M4-style post front sight ready to accept the optics of your choice or a back-up iron sight. Also included is one 30 round magazine built specifically to accommodate the 5.45 x 39mm round.
