The Victor Precision VP-25 is a CNC machined magazine to suit the Ruger American Rimfire Rifle, Ruger Charger Pistol, Ruger 10/22 Rifle, PWS / Volquartsen Straight Pull Rifles and the Christensen Arms Ranger Rifle. I had zero problems with this magazine and was amazed at just how smooth the loading and functioning of it was, best of all, it’s made right here in Australia!
