Has anyone else had issues getting enough eye relief with a CZ 457? I'm not sure what I'm doing wrong. I'm running length of pull spacers to make it match my Tikka CTR in KRG Bravo stock. The rail is an MDT 20 MOA version. The rings are Burris XTR Signature with the front right at the front of the rail with the scope slid as far forward as possible. It seems like I could almost use another inch.

With the scope installed the way it is and it still not providing enough eye relief I feel like I must be missing something. Any ideas?


 
Extension rings.Thay are L shaped. I use a couple of sets on my rifles. I have had similar problems with the turret or bell being where I wanted to put the ring. Usually I couldn’t get the scope back enough for me to see. I use Weavers. Basically L shaped with a longer base with the ring at one end.
 
Pretty amazing that doesn't provide enough distance for the eye relief with that setup, but you can get cantilevered rings to put the front even further ahead.
 
It could just be the angle of the pic, but is your LOP at max ? Just looks like the stock is short, XRS should go to 15" according to specs.

22 actions are very short. your front ring is where a non-cantilever rail would sit on a normal short action even though your rail cantilevers a good inch over the barrel. on top of that, your scope probably was designed for a long action. different scopes have different ideal set ups.

Once I have a scope figured out and mounted, i'll usually mark down the distance from the rear of the butt to the very back edge of the eyepiece diopter in both inches and centimeters. For example:

Schmidt und Bender 5-25x56: 29cm | 11 1/2"
Schmidt und Bender 12-50x56: 27.5cm | 10 1/2"
Schmidt und Bender 5-45x56: 27cm | 10 1/2"
Leupold ERT 8-25: 31.3 | 12 1/2"
...etc

If I move or dismount the scope, I probably won't have to mess around too much if I measure and mark it off.

I think that must be it, a very compressed action combined with a scope that has relatively long eye relief. I'll try adding to the length of pull like Buck1950 recommends and see where that gets me.
 
I’m running a 455 with the same stock and optic, it’s way forward as well.
Looks like you could get your front ring ahead a bit more? Flip the ring around if you have to.
 
Same here, wish I could move more forward the ,front ring, Used all the butt spacers just to get the better eye relief for the PST2, now my LOP is somewhere around 14”, a bit longer from my 13.5” normal, ok for bench but not the best for free standing position, it moves the center weight more forward,

There's enough room behind the turret, on the scope barrel to mount BOTH scope rings together.

Yes, I know, it just isn't done.

Well, I've had to do it for people before.

It allows you to use the equipment on hand and is very stable.

The only thing that you will have to do to make it work, is to lap the bottom ring base, to ensure they are aligned. When they're close together, alignment of the rings can be an issue. Not likely, if they're quality rings.

If your personal length of pull is normal, say around 13.5inches, then your neck may be longer than normal.

Easy way to check if the stock is the right length for you, place the butt into the crook of your arm, with a jacket on and reach for the trigger with your index finger.

If the pad on the tip extends more than halway beyond the trigger, your stock butt is to short.

If you're a stock crawler (speaking from experience) the very tip of your finger, at the trigger is about where you want the butt length to be.
 
I moved the front ring forward one slot. It's not bearing fully on the rail but there's still more clamping area than lots of other rimfire rings. I'll give it a shot and keep an eye on the torque values on the fasteners. I added all the spacers to the stock too which makes it 14" LOP which is a little longer than I usually use but very manageable. That seems to have the eye relief where I need it.

For what it's worth, if the length of pull were the same, the distance to the front of the rail is 1" shorter on the 457 versus the Tikka CTR, even with the slight cantilever on the MDT rail on the 457.

I filled out MDT's "New Product Request" form asking for a 1/2" extended forward catilever and threw in a suggestion for 30 MOA cant at the same time. If they could manage that at or below the price of the Area 419 rail I think they'd sell a bunch of them.

With the scope you have, ideally you'd install a 60MOA base on your rifle to maximize the usable elevation of your scope.

Between the rail and the Burris XTR rings I've got it set up with 50 MOA of cant right now. It can be adjusted to more if necessary.
 
Hmm, interesting; everyone is running the Athlon Midas TAC? I mean the rail is already cantilevered forward a decent amount; the longer you go, the higher the scope has to be mounted, which is why it's the length it is currently at. But it's good feedback.
