I just bought a CZ 455 American in .22 and am about to buy a scope and rings. I was thinking the Redfield Revolution 4-12x40 in Talley CZ high rings might be a good fit. I wanted a bit of extra magnification in case I get the .17 barrel in the future. I was just wondering if I'm going to run into bolt handle clearance issues on the scope with this combo? I have read that the 455 bolt throw is a bit long and hits some scopes if they have a large ocular housing.

Thanks in advance.

:cheers:
 
The Talley high rings for CZ are 0.600" (15.24mm) high. The objective lens OD on the Redfield Revolution 4-12 is 1.8" (45.7mm). That should provide plenty of clearance for the scope. The ocular lens OD is 1.6" or 40.6mm. There should be plenty of room for the bolt.
 
The Talley CZ rings are pretty high. You should have no trouble clearing the ocular and I'd say your 40mm objective bell will have nearly a cm of barrel clearance up front.

Is it going to be too high affecting cheek weld?

The Talley low rings are .350" high, while the high rings are .600". There's a .25" difference so the cheek weld should not be an issue. And it will not affect shooting or accuracy.

One of the problems too many shooters have when mounting their scopes is that they strive for as low a mount as possible. A scope that is mounted lower rather than higher seems to have greater aesthetic appeal. But that is never as important as how the scope height fits the shooter. The question that shooters should ask more often is not "is it too high?" but instead "is it comfortable for me?" I have rifles for which I have higher scope mounts than the minimum needed for clearance because they allow me to see through the scope better than otherwise.
 
I am of the opposite opinion or grauhanen myself and not a fan of Talley rings for their boxy look with square corners.
My preferance for rins would be Leupold Rimfire Rings (11mm) or the Burris Zee Rings in a Matte finish that usually matches the guns receiver.
But, again thats my flavor ...enjoy the gun and the scope combo for thwacking those pesky viscous gophers that are abut to over run the flat lands.

Be careful when buying Leupold or Burris rings for the CZ American. The 3/8" dovetail (which is 1/2" across the wide part and 3/8" inside the dovetail groove) has a 45-degree dovetail cut. Most of the rings out there including Leupold and Burris have a 60-degree cut. This causes the ring to clamp on the sharp part of the dovetail instead of mating along all of the surfaces as intended. The best solution in this case is to use factory CZ American rings or to use J&P dovetail adapters along with full-size Weaver style rings.

Can anyone tell me if the Talley rings have a 45-degree cut?

I'm not sure if there's a problem with the narrower non-American 11mm CZ dovetail, but that one is a 60-degree cut so it should work better with most aftermarket rings.
 
Well I think I'm going to reevaluate my choice of scope. I think I want something with either an AO or side focus. Back to the drawing board. Thanks for the input thus far guys.
