As far as the spring goes.
This is just me, but I don't use the spring on centerfire guns. I want it to slide in the rings and then pull it back and give it a twist to be sure it resets in the same position everytime (which it does).
I haven't tried this, but for rimfire, I suspect you can just put the stop on the other side of the front ring, and then push the scope forward if it seems out of position rather than pull it back into position after recoil, but having the spring would be better.
Even with a .22 it will slide in the rings if the stop is forward. Even if you forget to reposition the scope for a few shots, it doesn't make a huge difference in the point of impact. They are very precise instruments.
The difference between the externally adjustable scopes and an internally adjustable (if you can find one that tracks well and holds zero) is a couple of x's at 200,
There's a learning curve with them, and because they're pretty dynamic due to the movement, you kind of have to get them 'in tune' for the gun you're using, once you do they're dead nuts accurate and return to zero when taken off.

J Unertl Scope Serial Numbers Chart Printable
Hi, my name is Dewayne Greiner. I have made a great hobby out of buying, selling, and collecting the older target scopes. I really like the Unertl's, Lyman's, Fecker's and Redfield's 3200 scope. If you are in need of a nice scope, check out my Scopes for sale. I typically have a nice selection of good quality scopes. Unertl 2 Varmint Dehorned Scope 10x Blued Dot Crosshairs Rifle Scope Nice. J Unertl - $799.99. J Unertl Bench Rest, Target Rifle Scope 10 X Usa Nice. Freeland Spotting - $475.00. Freeland Spotting Scope Stand For Unertl Scopes. M40a1 M40a3 - $425.00. Examples of Unertl sniper rifles with star gauged barrels, from left to right serial numbers 1498646, 1496440, and 1464269 (Neil Duffy, Steven Norton, & Tim Plowman collections). The process of converting the National Match and Special Target rifles into Unertl sniper rifles would take six weeks, beginning in January, 1943 with the first rifles. Jul 25, 2019 The new scope was an immediate hit with anyone who could afford one. AS mentioned above, Fecker scopes made before 1924 had to be mounted with rings made by other makers. Something John Unertl had to cope with when after working with Fecker he set up his own shop years later.
