10 Round .22LR Spare Magazine

This is a Genuine Ruger Factory Accessory

BX-1, .22LR Calibre, 10-round Rotary Box Magazine is made of black plastic with steel feed.

It works with any factory original:

10/22 Rifle
SR-22 Rifle
22 Charger Pistol
.22 LR Ruger American Rimfire Rifle.

(This 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 a better choice for the 77/22.)
