CZ-USA | GENUINE FACTORY RIMFIRE MAGAZINE
The Factory Fit Your CZ Was Built Around.
The CZ-USA 12004 10-Round .22 LR Polymer Magazine is the genuine factory magazine for the CZ 457, 455, 452, 453 and 512. Same dimensions, same feed geometry and same polymer body as the magazine that shipped with your rifle—so you can load ahead at the bench, keep a spare in the bag and spend more time shooting.
Every serious rimfire shooter learns the same lesson eventually: one magazine is never enough. Extra mags mean less time thumbing rounds between strings, a backup when one goes missing in the range bag, and a ready supply for training days, matches and squirrel woods alike. With the CZ 12004 you're adding capacity without adding variables—it's the original CZ design, built to the factory's own specifications for reliable feeding in the rifles it was made for.
Factory Polymer, Proven Across CZ Rimfire Generations.
CZ's 10-round polymer magazine has served the 452 and 453 for years and carries straight through the 455, 512 and today's CZ 457. That shared footprint is a big part of why the CZ rimfire platform is so easy to live with: one magazine pattern across multiple rifles. The lightweight polymer body is tough enough for everyday use, and the 10-round capacity hits the sweet spot for plinking, hunting and practice sessions. For a slimmer, more classic option, CZ also offers the CZ-USA Blued Steel 5-Round Magazine, a favorite with shooters who prefer a flush steel mag on a sporter or hunting rifle.
Ready to Step Up? Billet Aluminum Magazines for the CZ 457.
For PRS rimfire, NRL22 and other timed match work, many CZ 457 shooters run a mix of factory polymer mags for practice and machined billet magazines for competition. We stock both of the names CZ 457 competitors ask about most. The L3i CZ 457 Billet Aluminum 10-Round Magazine and the higher-capacity L3i 13-Round Magazine deliver a precision-machined aluminum build, while the Position7 CZ 457 Billet 10-Round Magazine and Position7 13-Round Magazine round out the lineup for shooters who want extra rounds on the clock.
Pair your magazines with a smoother, faster reload. The DIP CZ 455/457 Aluminum Magazine Well replaces the factory polymer guide with machined aluminum, and the DIP Mag Well & Bumpy Release Combo adds a more positive magazine release in the same package.
With more than six years building and supporting CZ rimfire rifles, Pete's Pillars manufactures and stocks the parts that make a CZ shoot and handle better—from bedding pillars and bolt components to the magazines that keep it fed. Explore the full lineup in our CZ 457 Parts & Upgrades Collection.

Frequently Asked Questions
Fitment, factory versus billet magazines, and getting the most from your CZ rimfire.
Which CZ rifles does the 12004 magazine fit?
The CZ-USA 12004 is the factory 10-round .22 LR magazine for the CZ 457, CZ 455, CZ 452, CZ 453 and CZ 512 rimfire rifles. One magazine pattern works across all of these models.
Is this a genuine CZ factory magazine?
Yes. This is the original CZ-USA magazine, part number 12004—the same design and polymer construction that ships with factory CZ rimfire rifles. It is not a third-party copy.
Will it work in my .22 WMR or .17 HMR CZ?
No. The 12004 is built for .22 LR (and .17 HM2). Magnum rimfire CZ rifles in .22 WMR and .17 HMR use a different, larger magazine and will not accept this one.
Should I choose the polymer 10-round or the steel 5-round magazine?
Choose the polymer 10-round for more capacity at the range and in the field. The CZ-USA Blued Steel 5-Round Magazine sits lower and slimmer, which many hunters and sporter owners prefer. Plenty of owners keep both.
How does it compare to L3i and Position7 billet magazines?
The factory polymer magazine is the dependable, lightweight standard for everyday shooting. Billet aluminum magazines from L3i and Position7 are machined specifically for the CZ 457 and are popular with competitors, including 13-round versions for longer match stages. Many shooters train with factory mags and compete with billet.
Do I need a new magazine well to use this magazine?
