CZ 457 / CZ 512 / CZ 455 Polymer Magazine – .22 LR (25-Round)

This factory-style polymer magazine is made to fit CZ rimfire bolt-action and semi-automatic rifles chambered in .22 Long Rifle, including CZ 457, CZ 512, and CZ 455 models. With a 25-round capacity, it provides extended ammunition capability over standard shorter magazines, making it ideal for target shooting, plinking, and range sessions where a higher round count improves convenience.

Key Features

Large Capacity:
• Holds up to 25 rounds of .22 LR ammunition, giving you more shots between reloads compared with smaller 5- or 10-round magazines.

Lightweight Polymer Body:
• Constructed from impact-resistant polymer for durability and corrosion resistance, while keeping overall weight low.

Reliable Feeding:
• Designed with a quality follower and spring system (often stainless steel spring with polymer follower on many OEM style mags) that promotes smooth, consistent feeding of cartridges into the chamber during repeated cycling.

Extended Shooting Sessions:
• The high round capacity makes it a good choice for range practice and competitions where frequent reloading interrupts shooting flow.

Original CZ Design:
• Produced as a genuine CZ USA-compatible magazine, matching original factory specifications for fit and function on supported models.

Compatibility

This magazine fits the following rimfire rifles chambered in .22 LR:
✔ CZ 457 series
✔ CZ 455 series
✔ CZ 512 (semi-auto)
(Some older CZ rimfire models with the same magazine well are also compatible.)

Performance & Practical Use

This extended magazine expands your shooting time by allowing more rounds between reloads — a benefit during long range sessions or informal shooting competitions. Its polymer construction keeps it lightweight yet strong, and many factory-style designs use quality springs and followers that help smooth feeding even when the magazine is fully loaded.

Whether you are plinking, practicing for competition, or doing fun target drills, the 25-round magazine lets you stay focused on shooting rather than frequent reloads. Just ensure your firearm’s magazine well is clear of obstructions and that the magazine inserts and locks firmly before firing.

Best Suited For

✔ Owners of CZ 457, CZ 455, or CZ 512 rifles in .22 LR
✔ Shooters who want extended capacity for range sessions
✔ Target practice and informal competition where reloading slows the pace
✔ Plinking or recreational shooting with minimal interruption

User Tips

Confirm Fit:
Before use, ensure your rifle is one of the supported models listed above — magazines may differ between calibers and rimfire variants.

Load Rounds Evenly:
Fill the magazine with .22 LR rounds gradually and evenly to help maintain spring life and feeding reliability.

Routine Inspection:
Periodically check for dirt or debris inside the magazine or mag well — keeping these clean can help prevent feeding issues.

Storage:
If storing magazines for long periods, consider unloading them to reduce constant spring compression and extend spring life.
