Made in the USA using black plastic and a steel feed, the BX-1 magazine will work with any factory original 10/22® Rifle, SR-22® Rifle, 22 Charger™ Pistol, and .22 LR Ruger American Rimfire® Rifle. The magazine will also function in the .22 LR Ruger 77/22® Rifle, but the contoured base does not match the profile on the bottom of this rifle; the JX-1 Rotary Magazine is recommended for this rifle instead.
WARNING: Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead and other substances known to the State of California to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands thoroughly after exposure.
