For a good bolt action 22lr, CZ457?

[King31]

CZ 452 is a sweet shooter. I put a Vortex Diamondback 2-7 on mine and it’s leaps and bounds better than all the 22s I’ve shot in the past. I bought mine new a few years ago when Whittaker’s placed a special order but it looks like even they are out. I can’t comment on the other suggestions, but I’m sure they would be great as well.

I’ve got a 452 with the Super Match barrel that I can’t wait to shoot when it warms up. You really can’t beat CZ price/quality.

I sure hope they're good
Currently waiting on a MTR to arrive.

Wholesale Hunter still has some 452's available.

The biggest "complaint" with the 455 was that CZ got rid of the threaded barrel/action and went to 2 set screws and a "quick change" barrel. It's proven reliable at this point.

With the 457 keeping the same barre/receiver interface and getting a 60 degree bolt, there is no reason to get a 452 or 455. It'll be a good reliable gun if you want a CZ.

Personally, I'm going to give the Tikka a try once they're more available.

FWIW I have the older 455 and w Burris alloy .22 rings the bolt handle clears my scope bell (Leupold).
The rings are medium, and 3/8.
But 30 in lbs makes em work

I have the 455 tacticool with factory cz rings and a Nikon prostaff rimfire. No clearance issues at all. I love the rifle, it’s my suppressor host and is tons of fun. Accurate little guy
