The Plinker Tactical M&P 15-22 magazine is a 22 long rifle, polymer, 35-Round magazine. This magazine is specifically designed for the Smith & 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 magazines, but give you an increased capacity for longer shooting sessions. These mags are specifically designed to work with the Plinker Tactical magazine loader. The magazines are constructed of impact and solvent resistant polymer and are 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.
