Description
Three genuine factory Ruger BX-1 magazines pack serious value for any rimfire platform running .22 LR. These aren't aftermarket compromises—they're the same rotary magazines Ruger engineers designed for the 10/22 family, and they've earned a reputation for just working, every time.
What Makes the BX-1 Rotary Design Stand Out
Unlike traditional stack-style magazines that can bind when cartridge rims overlap, the BX-1 uses a rotary system where each round sits in its own defined slot. This mechanical advantage means more reliable feeding across all kinds of ammunition, even with different bullet profiles. The rotating spring maintains consistent tension without the weak-point failures you see in higher-capacity inline designs. That's why people trust these for anything from plinking at the range to small game hunting.
Built Tough, Simple to Maintain
Each magazine features a black polymer body reinforced with steel feed lips—durable components engineered to endure thousands of rounds without wear or jamming. The red polymer follower gives you a quick visual indicator when you're running low on rounds. Construction is clean and straightforward: no complicated internals to fuss with, no springs that lose tension over time. They clean up easily and keep feeding reliably whether you've been out shooting all afternoon or storing them in your gear bag.
Real-World Compatibility Across the Ruger Rimfire Lineup
These work with factory original 10/22 rifles, SR-22 rifles, 22 Charger pistols, Ruger American Rimfire rifles, and 77/22 rifles. Getting three magazines means you've got fresh options rotating through your shooting sessions without downtime reloading.

Frequently Asked Questions
Will these BX-1 magazines fit my older 10/22?
Yes. The BX-1 design has been compatible with 10/22 rifles since the platform's introduction. You can mix and match these with older original magazines without any issues—Ruger's been using the same basic magazine dimensions across the entire product line.
What makes the rotary design better than other .22 magazines?
The rotary system places each cartridge in its own slot, preventing rim overlap and the binding problems common in stack-style magazines. This means more reliable feeding regardless of bullet shape or ammunition type. The rotary spring also maintains consistent tension without losing pressure like ribbon springs in higher-capacity magazines.
Can I use these BX-1 magazines in my Ruger American Rimfire or SR-22?
Absolutely. These work across the entire Ruger rimfire platform—10/22 rifles, SR-22 rifles, 22 Charger pistols, American Rimfire rifles, and 77/22 rifles. Factory magazines fit factory receivers perfectly.
Are these factory Ruger magazines or aftermarket?
These are genuine factory Ruger BX-1 magazines, not aftermarket. They're made to Ruger's exacting specifications using the same materials and tolerances as the magazines that come with new rifles, which is why they're the standard recommendation among experienced rimfire shooters.
