The CZ 452, CZ 453, and CZ 455 .22LR 10-shot polymer magazine is a detachable rimfire magazine designed to provide increased capacity while maintaining reliable feeding performance across these CZ rifle platforms. Constructed from durable polymer, it offers a lightweight yet resilient alternative to metal magazines, making it well-suited for regular use in a variety of shooting environments. Its 10-round capacity allows for extended shooting sessions with fewer reloads, which is particularly useful for target shooting, training, or informal range use.

Internally, the magazine uses a single-stack configuration that aligns each .22LR cartridge in a straight column. This design ensures that each round is presented at a consistent angle for feeding into the chamber, which is critical for rimfire ammunition due to its smaller size and sensitivity. The spring and follower system are engineered to maintain steady upward pressure throughout the full capacity, helping to ensure smooth and consistent cycling from the first round to the last. This contributes to dependable operation and supports the accuracy and reliability associated with CZ rimfire rifles.

The polymer body provides resistance to corrosion and reduces overall weight, while also being less prone to denting compared to steel magazines. Many versions include a slightly textured surface or subtle transparency, allowing for better grip and quick visual checks of remaining rounds. The magazine is designed to lock securely into the rifle’s magazine well and can be easily inserted or removed as needed. While it extends slightly below the stock due to its higher capacity, it remains compact enough for comfortable handling in both range and field conditions.
