I am trying to mount a Vortex Diamondback Tactical Scope on a CZ 457 that I just bought. The CZ 457 has a 11mm dovetail rail for mounting and does not have screw holes for a piccatiny rail. I have been told the best thing is to get a gunsmith to drill holes for screws. I am reluctant to do that, as there is no going back once you drill. Should I be worried about drilling, or is really no big deal? Second, what mounting hardware might let me mount the scope without drilling? Some research suggests a 30mm ring, high, might do it. Anything else I should consider. I will be using the setup for target, silhouette shooting.
Mounting a Vortex Diamondback Tactical Scope on a CZ 457

There are pic rails available that slip over the 11 mm rail for scope mounting. Available with slope for shooting farther or without slope. Burris also makes rings for the 457 series. I wouldn’t be drilling and tapping any holes in your rifle. Lots of site sponsors have what you need. CSC, GBT or look on the EE.
Lots of rail available for the CZ457 11mm dove tails, no drilling required, I have one on my 457

I use SportsMach ATP34 rings which mount directly to the dovetail. This solution is cheaper and also provides cant adjustment.

While I admit that mounting an adaptor that then allows the use of Picatinny rings "might" be stronger...I really wonder how worthwhile that is. Depending upon your intended use, how strong do you really need it to be? I have a number of .22 plinkers and target shooters that never leave the back deck. Most of them are equipped with quality rimfire-dovetail rings that clamp directly onto the receiver grooves. It's a very clean-looking set-up, allows lower mounting, and depending upon what you may have floating around in your parts drawer it can be much less expensive as well.
Sure, if you want an angled MOA-type mount for long range, you must go the adaptor route. If you're taking your rifle into combat...and the Powers That Be make it clear that these are weapons of war!
...then a base attached to the receiver with screws is likely a better choice. Another good choice would be one of the numerous one-piece base+rings units that are marketed and sold for airgun use. They attach to the receiver dovetails by clamping, but the clamp is a full-length piece usually held on by a number of beefy screws.
But a base that simply clamps to the tiny receiver grooves and then supports Pic rings sounds like it just might be the worst of both worlds for a casual .22 plinker.
I'm a big fan of SportsMatch rings. Check out the Airgun Source Canada website. They have a huge selection of SportsMatch rings and will almost certainly have what you need.

Don't drill anything! No reason and you will only hurt resale on rifle and potentially performance as you are mounting onto a flat dovetail. Your buddy, while well intentioned, is likely not familiar with the 457.
As others have said, tons of rails and rings available.
If you go for a rail you will probably be fine with med rings. I have a 50moa MDT rail and medium mdt rings on a 457 with an Arken EP5 which is a pretty big scope. If you are not having a rail you may need high rings.
I would think a 20moa MDT rail and medium MDT rings would work well for you.... but best thing to do if you are unsure would be to buy the rail you want and then go into a store with your rifle and get rings that give you the correct height.

Thanks. I wasn't too keen on drilling and glad to hear someone thinks the same.
