The Magazine Built for Competition
The CZ 455/457 platform is highly popular among precision rifle shooters, but factory magazines often fall short when it comes to durability and usability in competition. This 22LR 10-round magazine, CNC-machined from a billet of aerospace-grade 7075 aluminum, is designed specifically to overcome those shortcomings and give you an edge on the clock.
 
Designed by a World Champion
This magazine has been designed by Roman Konečný, 2025 World IPRF 22LR champion in the Senior division. It was meticulously tested with thousands of rounds to ensure unparalleled reliability and helped him win this amazing event.
 
Innovative Geometry and Handling
Unlike standard high-capacity CZ magazines or aftermarket aluminium mags, this design features a unique internal geometry. Cartridges are slightly angled, which reduces the overall curvature of the magazine body. With a straighter profile, the magazine doesn’t extend that far forward and doesn’t interfere with your shooting bag, barricade stop or chassis.
 
Easy Access to the Magazine Release
One of the biggest challenges with longer magazines in the CZ platform is accessing the mag release lever, which is located at the front. Combined with barricade stops on many chassis systems, this can make reloads frustrating. By reducing curvature and refining the profile, this magazine makes it significantly easier to reach and operate the mag release quickly and reliably. This is especially important in competition chassis like the MDT ACC, where the magazine cavity is very tight and extended magazines often block access to your magazine release lever.
 
Built to Last, Built to Win
Precision-engineered from premium 7075 aluminum, this magazine is built to withstand the toughest competition environments. Every detail is optimized for function and reliability, giving you the confidence that your gear won’t hold you back when it matters most.
