CZ-USA 452/455/457 .22LR Single Shot Adapter

This single shot adapter/magazine fits my CZ457 as well as most CZ .22LR rifles. It works best if you start the nose of the round into the chamber. The adapter's job is to support the brass portion of the cartridge, which it does without issue. This is made from polymer which has proven to be very capable material for different parts of a firearm, and its very durable, having used this item for 1,000's of rounds. Thanking Bud's for this item as it is very hard to find.

I am satisfied with the product. I tested it in the magazine well and fit and function are good. If you are using this for field work I found no issues.

This magazine is the single shot version of the 5 round magazine. Exactly the same baseplate and shell as the 5 round magazine. It appears that the single shot feed ramp was glued to the body of the magazine and is not removable. It fits and functions perfectly and is almost as fast to load as the multiple round magazines.

Very well made OEM mags. No problems reloading the 4 tine and then shooting. No hiccups.

Works well. I bought to see if I can shoot better groups by loading cartridges individually, but haven't really tried yet. When I do I'll update this review. Bud's was great as usual!

Does the job! Cant ask for anything more.

Kind of expensive for a piece of plastic. But the fit is perfect and it works exactly as it should. So it's worth the money.
