If you're running a left-handed Ruger 10/22 in .22 LR, reliable magazines are non-negotiable—and these BX-1 rotary magazines deliver exactly what your rimfire needs. This three-pack of Ruger 90979 left-hand magazines gives you spare capacity on the range or in the field without the hassle of swapping between right-hand designs. Each magazine holds 10 rounds of .22 LR ammunition and features Ruger's proven rotary design, which uses a unique rotor to separate and feed cartridges reliably, shot after shot.
The BX-1 rotary mechanism is what sets these apart from simple box magazines. That rotating follower keeps rounds organized and under consistent spring pressure, so you get smooth feeding and fewer jams—especially important when you're counting on your 10/22 for small game, target work, or just pushing rounds downrange. The black plastic construction is lightweight and field-ready, and the left-hand orientation means the mag release and loading port work naturally for southpaws.
Getting three magazines in one pack makes sense: keep one in your rifle, one in your pack, and one on the bench. For anyone serious about their 10/22, having matched, reliable mags across your rotation takes the guesswork out of ammunition management and lets you focus on what matters—accuracy and fun.

Frequently Asked Questions
Will these left-hand magazines work in my right-handed Ruger 10/22?
No. These BX-1 magazines are designed specifically for left-handed Ruger 10/22 models. Using them in a right-handed rifle will result in improper feeding and function.
What makes the rotary design better than a standard box magazine?
The Ruger rotary mechanism uses a unique rotor that physically separates cartridges within the magazine, keeping them organized under consistent spring pressure. This reduces friction on rim-fired ammunition and promotes smoother, more reliable feeding—a real advantage with .22 LR rounds.
Can I use these magazines for hunting or just target shooting?
These magazines work for any application where your left-handed 10/22 is used: target practice, small game hunting, plinking, or competition shooting. The rotary design's reliability makes them suitable for field use.
Why does a three-pack of magazines make sense?
Having multiple magazines means you're never stuck reloading—keep one loaded in your rifle, one in your bag, and one as a backup. It streamlines practice sessions and field trips by eliminating downtime.
