Perfect addition to cz457 - CZ-USA CZ 452/453/455/457/512 .22 LR/ .17 MACH 2 10-Round Magazine

I have owned my CZ457 for about a year. Love the rifle but have wanted magazines with more capacity than the 5-round single one that came with the rifle. The 10 rounders a a very nice upgrade. They are plastic but feel like they do the job. No issues with feeding. The magazines were on backorder for months (as expected) but Optics Planet continually provided updated expected shipping dates. I have no reservation backordering because i did receive the product as ordered and payment doesn’t happen until items are shipped.
