This single shot .22LR magazine insert is a loading device for converting magazine fed .22LR CZ rifles to single shot use, providing an angled loading platform for manual loading.
Made from a tough ballistic nylon polymer, it's basically their 5 round magazine fitted with a solid core that features a small bullet tray on the top, instead of a spring mechanism.
A factory original from CZ for the CZ 452, 453, 455, 512 and 513 rifles. Also compatible with most BRNO, Norinco and Puma .22 models.
Factory replacement parts are manufactured to the exact same specifications and tolerances and use the same manufacturing materials as the standard ones which come with the rifle, ensuring excellent fit and reliable operation.
