For 8mm mausers a good cheap fixed power scoped is a Weaver K6 6X available at Midway for around $140. We have used these for years on Mausers.
Kalinka scopes used to be real good. The last few have problems with bubble like fractures in the reticle lens.
Not recomended for 8mm recoil.
Kalinka has a one year warranty and honors it is you have your receipt.
Weaver K6 scopes have very fine cross hairs and a compatible for long range target shooting as well as hunting.
They also look well on a Mauser if in Matte not gloss. Sleek and complement the rifle well.
Kalinka reticles come in a variety. Post reticles are hard to used because the post blocks out the target on hold over shots. Unless the scope is mounted upside down.
Simonov and Dragunov reticles with range finder are inverted V and work well for those that like them.
Kalinka's new line of Mildot cross hairs are exc. VERY fine cross hairs that do not block out anything with fine mildots for range adjustment in a heart beat.
Kalinka has a new Mildot cross hair in PSOP that comes with a weaver rail type mount, requires weaver type mount, that John's or Iron Elite should accomidate.
Be aware that Iron Elite has had communications problems recently with customers.
The scope is also very beefy and is advertised as OK for 8mm recoil.
The beefy is not good for weight and balance.
The K6 Weaver type scopes are light and sleek and well balanced and has fine cross hairs that have held up for years of shooting for us.
We have boxes full of cheaper N C star and other types of scopes that have all failed in one way or another.
Also on a side note.
The scope mounts that are like the Iron Elite and John's new mounts were tried and rejected because of balance issues.
Anything that attaches to or replaced the rear sights just didn't feel right for balance.
This is just our opinion and others may have good luck with using that kind of set up.
I used one of the older 4X Kalinka type scopes for years on a 303 Enfield JC without any problems.
So it seems the newer scopes used a different process to glue the reticle lenses and have now a recoil problem.
If you like the Kalinka scopes real well, try it, they have a one year warranty, make sure you keep the paperwork.
I had one new Kalinka 6X with the new Mildot fine reticle develope bubble like fractures, just from taping the mount with a brass hammer to line it up. There seems to be a mfgr. problem with the newer scopes.

The above link are the PO type scopes that have the recoil problems, in 8mm. Older models did not have this problem.

These PSOP scopes are advertised to hold up to 8mm recoil. They come in 6X or 8X They are a bit beefy, "large" They should fit on John's weaver rail.

This K6 scope is on sale for under $130 has worked well for hunting and target shooting M48s for years. Cross hairs are very fine, not bulky as pictured.
Most scopes under $300 will not stand the test of time. They may look good, but few hold up to recoil and hunting enviroments from our experience.
The K6 Weaver is an exception, as are the older PO Kalinka scopes.
