Ruger

The 15-round BX-15 Magnum magazine incorporates technologies that have made the .22 LR BX-15 and BX-25 magazines famous and also features the same feed lip geometry that has proven reliable in the 9-round JMX-1 rotary magazine. The BX-15 Magnum is compatible with Ruger 77/17 Ruger 77/22 and Ruger American Rimfire rifles chambered in .17 HMR and .22 WMR. The stainless steel feed lips and constant force spring combine with a high-lubricity polyacetal anti-tilt follower and durable glass-filled nylon magazine body to make the BX-15 magazine rugged reliable and easy to clean.
