BRNo 21H Scope Help

I've a European tweaked 21.
They took some type to grinder ( my bet on a flapper style unit) and ground it to fit.
Mine has a 1" tube weaver on a Mauser Short side rail though...that might change things a bit too

The bolt on mine has had material removed but it doesn’t correspond with any scope dimensions I can lay my hands on.

SRR typically sit high, FYI.
I'll see if there is shot of it on imgur.

This help at all? It's pretty high as you can see. Might help explain your difficulty if this was the original set up.

Tokguy, thanks for the pictures. Your rifle appears to be a sporterized 98, my rifle is a 21H so bolt dimensions are quite different. At this point a side mount might work, but as I’m reluctant to spend big bucks on second bolt or bolt modification, Im also not willing to drill and tap for a side mount.

Thanks to everyone who has chimed in so far. A few people have made measurements and posted them and a few more have measured and PMed me various scope ocular dimensions.

The scopes that seem likely that I do not have dimensions for so far are :

Leupold Ultralight or Compact in any magnification
Leupold FX II in any magnification
Weaver V3 1-3
Burris Compact 4x or Burris 4x Timberline

I have now determined that the M8 4 and 6 powers are a “shade” too big, they are Nominally 1.5” .

Takujualuk, that is good information thank you. Do you know the model number or product number of the scope? I have a lead on a small Burris currently but a fixed Leupold would suit me as well.

It's a FX mini 4..current number is (FX-I RIMFIRE 4X28 FINE DUPLEX
Part # 58680) They are set at 60 yards for parrallax but they used to make a big game version I believe. In any case my 7x57 21H is sub-MOA at 100 yards with factor 173 S&B ammo. I have a mini 6X Burris on my 8X57 and it works but it has the bent bolt handle, so is less sensitive to the small eyepiece

It's a 46, lol.
Sorry about the mixup... better have tea here.
 
A friend suggested someone must make a CZ-Weaver adapter, would a standard length Rail for a 550 work? I have a second set of High weaver compatible Warnes In bound for something else and could possibly go that route.

Considering the alleged cult status of the Brno 21/22s it would seem few see the woods, atleast with scopes mounted anyway.

The especially irksome part of the whole situation is the fellow I bought the rifle from had originally agreed to include rings with the rifle (that allegedly worked with some scope or another) but when it showed up they were absent along with the rear sight. The rear sight arrived thankfully and I’ve found the rifle accurate with my poor eyes. But that makes me extra eager for a scope.

Fix or replace the bolt ... a scope mounted 2 inches high is ridiculous...

I have a had a couple Brno 21/22's with unaltered bolt handles. I don't mind a high scope, but it's clearly a personal choice. My solution was to buy some 23mm high Rusan rings from Optics-Trade in Solvenia. They were expensive and heavy, but they worked great for the 21/22s and alleviated the need to bugger with the bolt handle.
 
I didn’t have a spare hour to percolate through all the mounts on Optics-trade but I suspect they would be very high but work.

Thanks to several excellent CGNers I have a scope in the mail as we speak.

It has been verified to work by several people. I will figure out how to post pictures when it has arrived and is mounted.
 
The Saga of the scope mount continues. I assembled High Warne Rings and a Leupold Compact 4x with an Ocular of 1.35” . This combination was reputed to be functional.

It looked like a sure thing, but the bolt still drags ever so slightly and sticks if not operated exactly straight. Not a suitable set up for a hunting rifle in my opinion.

A friend had a use for the rings luckily. Now I am checking out various manufacturers literature to find a Set of Easily available rings that is higher than the .535” of the Warnes.

Millet is slightly taller at .590” but I’d feel better with even more height.

If anyone has experience or a measurement for Other makes of High CZ/Brno rings I would love to hear more.

At this point I am perhaps delaying me inevitably order Xtra high rings from Optics trade. The price and wait time are the main deterants.
 
I finally ended up with a set of Millets that clear the bolt.

Once this hunting season is over, the Brno is off to the smith to have the bolt recontoured to clear a larger variety of scopes on the Warne mounts.
 
The Leupold compacts and ultralights have an eye piece of 1.36" OD
Some have short tubes however. The Leupold 6X compact I have on my ZKW hornet is 6" of tube and 1.36" eyepiece and fits. Barely.

 
I had a steel weaver 4x on mine, it cleared the unaltered bolt with high warne rings. The low comb and high rings made for an undesirable chin weld. If it was a keeper I’d have your bolt altered by a good smith and run low rings.
 
The bolt had been altered before I got it. I just want the gun up and running to hunt with and shoot a bit before I decided how much work I wanted to put in to it.

For anyone else’s information the M8 Compact 4x is 1.35” at the widest on the ocular and would still not clear High rings if the bolt was unaltered.
