The Plinker Tactical M&P15-22 magazine is a polymer, .22LR, 35-round magazine, designed specifically for the Smith and Wesson M&P 15-22. The magazines have the look and feel of real 5.56x45mm NATO magazines. The Plinker Tactical magazines function just the same as factory magzines, but give you an increased capacity for longer shooting sessions. These mags are designed to work with the Plinker Tactical magazine loader. Magazines are constructed from impact and solvent resistant polymer and sonically welded for long term durability. The solid mag body without exposed springs or loading tabs keeps dirt and debris out increasing reliability and long term durability.
