I have had this gun for over a year, but never been happy with the action, although the accuracy is exceptional.
The bolt started to just come straight out the back in my hand on cycling after about 8 weeks and I took back to shop who fiddled about and didn't do an awful lot, then returned it to the importer, before returning to me and it was ok for about 3 days. I then had the Timney fitted to improve the stock trigger and Riflecraft had a look.
It was much better trigger wise but still occasionally cycled out the back so to speak. Now it does it every time unless you are very gentle and also self-dishcarges to boot, so is bloody lethal from that perspective. I'm going to take it in to a gunsmith again, but to be honest I have lost confidence in the gun.
Anyone else had problems with the CZ455? It seems to be universally praised, so maybe I got a Friday gun?
EDIT: it's the 22lr
