The Ruger 10/22 is America's favorite .22, and we love it as much as anybody-but the factory 10-round magazine leaves a little something to be desired. This ProMagA(R) Drum Mag gives your 10/22 a big shot of "cool factor" and a huge capacity boost-so you can load it on Sunday and shoot all week, as the old saying goes. It's quality-made in the USA, and features a smoky polycarbonate drum body that looks pretty cool, too.
