Yes, CZ .22 magazines, 5 & 10 rounds work in the Norinco which is a close copy of the CZ452
There are lots available. Just do a google search or look at CGN sponsors. They come in steel and polymer, your choice. The Tillsonburg Gun Shop shows them in stock.
Norinco copied the Brno No. 1 for their rifle and the CZ452 is a modern version of the Brno No. 1
