>>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 the
Ruger Precision Rimfire
chambered in .17 HMR and .22
WMR, 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.
