BX-1 10-round, .22 LR caliber magazine is made of black plastic with steel feed and works with any factory original 10/22 Rifle, SR-22 Rifle, 22 Charger Pistol and .22 LR Ruger American Rimfire Rifle.

Magazine will 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 (#90057) is recommended for this rifle.
