Description
This is the genuine Rossi RB22 magazine that comes factory standard with your rifle. Whether you need a backup when your primary magazine wears out or want to load up multiple mags for a range day, this 10-rounder gives you solid performance without the guesswork of third-party alternatives.
Quality Steel Construction Built to Last
You're looking at a welded steel body with a matte black finish that stands up to regular use. The magazine isn't flashy, but it doesn't need to be. The precision-machined feed lips lock tight into your RB22's magazine well with virtually zero wobble. That snug fit means more reliable feeding and less frustration downrange. A steel wire spring provides consistent upward pressure on the follower, and the high-visibility green polymer follower makes it easy to track your remaining rounds at a glance, especially in low light.
Optimized for the .22 LR Round
This magazine is purpose-built for .22 Long Rifle ammunition in your Rossi RB22 bolt-action rifle. Unlike one-size-fits-all magazine designs, this one delivers the correct feed geometry and spacing for rimfire cartridges. The geometry matters more than you might think with smaller rounds, and Rossi got this right from the factory. Compact and lightweight at just 0.11 pounds, it won't weigh down your range bag or hunting pack, and the 6.95-inch length fits easily into pockets or pack side pouches.
Worth Keeping Spare
Magazines are wear items. Springs lose tension, feed lips can get dinged up, and plastic followers can crack. Having a spare OEM magazine protects your investment in the rifle itself. It also means more uninterrupted shooting time instead of constantly reloading the same magazine shot after shot.

Frequently Asked Questions
Will this magazine work with other .22 rifles?
This is specifically designed for the Rossi RB22 bolt-action rifle. While some users report compatibility with similar Mossberg models, we recommend verifying fit on your specific firearm first. The feed geometry and locking lugs are engineered for the RB22 platform.
What's the difference between this and a third-party magazine?
Factory OEM magazines ensure mechanical compatibility and consistent feeding geometry that's optimized for your specific rifle. This magazine goes through Rossi's quality control and is built to the same specs as what ships with the rifle. Third-party alternatives may save money upfront, but they can introduce feeding issues down the road.
How many of these should I have on hand?
That depends on how much you shoot and how you use your rifle. Most range users keep 2-3 loaded magazines so they can keep shooting without constant reloading. Having at least one spare protects you if your primary magazine gets damaged or when it's time to retire a worn spring.
Can I take this magazine apart to clean it?
These are press-fit assemblies designed to be user-resistant. We don't recommend disassembly since getting it back together properly can be tricky. If your magazine needs maintenance, it's better to contact a gunsmith or reach out to the manufacturer for guidance.
