I'd personally pass on 455. Unlike it's predecessors, the barrel is "pinned" (they use grub screws) to the receiver. The CZ452~the barrel is threaded to the receiver and in most people's opinion, that's a far superior..more robust set-up with better accuracy potential. I've never owned/used/shot a 453 but as far as I know, the only difference between IT and the 452 is a set trigger. The 452 and 453 are both no longer in production, but can be found new/used if you look. Expect to pay more for a 453, but it might save you your trigger job!The YoDave trigger kit for the 452 is a nice addition, and not expensive.
I'm not saying 455s are not good guns, but I'm of the STRONG belief this is simply a cost-cutting measure on CZ's part, and marketed as being an "advantage" to people wanting to switch calibers/barrels. No thanks!
Scope~I've had very bad luck with Crossfires, and had to involve Vortex's warranty. I upgraded to a Diamondback (4-12x) as a replacement for one of them, and it did it's job. I'll never buy a Crossfire again. I've had 2~a first, and a second generation. What I DO have on my CZ452 Varmint/gopher gun is a Sightron S1, 4-12 HHR. Got it from Hirsch Precision~CGN sponsor. It's been a very solid scope so far, and I can tell you thousands of gophers can vouch for that. Or...could...![]()
I think having rifles with interchangeable barrels might be partially driven by the fact that in some European countries there is a limit on the number of firearms you can own.
