Mounting CZ 457

I have purchased a CZ 457. Going with a PST GEN 2 scope looking for what is the best mounting options. Is it the area419 scope base or is something else a more reasonable option. Could a guy go with just scope rings? And still get the elevation that is needed?
 
The 419 base is super nice and well built. But it is a little tall. There are some other threads already that list all the options. But I believe the Dip Rail is the other option people recommends.


I looked at their rail, the one thing that is keeping me from that is that I would need to drill into the action. The pilot holes are there but they are not completely drilled. Not something I really want to deal with. Taking it to someone is an option it’s just another cost that I really didn’t want to put into a trainer.

How would the set screw locking into the dimple on the receiver not be sufficient on a .22lr?

After I installed my DIP rail, with the scope attached, I dropped my rifle from about 2ft butt down to see if the rail would budge. It didn’t move.
 
I’d just feel better if it was screwed in if I was going that route I think. I think I’ll just bite the bullet and buy the 15moa area419. Probably a safe bet plus it comes with the bubble level I think.

If you plan on shooting beyond 200 yards, you should probably get a 20moa. With a 20moa and viper PST gen2, I was barely able to get to 300 without holding over.

i can speak from personal experience. i had the dip rail on my 455 for over a year with no issues. i'll be the first to admit i got lazy and didn't check my gear before every match, things ran fine until one match they didn't. i couldn't hit anything consistently. after the match i got home and checked over my rifle completely. the rail had moved almost an 1/8th inch. more than enough to throw everything off. i have no idea how it happened, except it got knocked off of a rifle rack (and of course i didn't check it) about 3 weeks prior.

so beware, just because it didn't move this time, doesn't mean it won't move in the future.

just my .02 but i would look at the bscar rail if you don't want a high profile mount or the area 419 rail if you don't care about height
 
Does the 455 have dimples in the action to seat the set screws? Isn’t the BSCAR rail identical to the DIP? It uses the 4 set screws to lock into the dimpled action.

my mistake i was thinking of the EGW rail, not the bscar.

the bscar is a good rail as well but it does use the set screws.

and no the actions are different i was simply illustrating the issue i ran into with the set/grub screws. sorry for the confusion
 
Gotcha. The 457, with its dimples, lock the rail from moving forward or back and left to right, as long as the set screws are seated in the dimples. It’s a much more solid mounting system than the older model.

Still confused as to why they made so many great changes over the 455, but didn’t drill and tap the action for a rail??? The dimples are a huge improvement but to drill and tap would have been a no brainer in my mind!
