I wanted to get this posted sooner but I had a family function.
No need to apologize or be frustrated, I think the goal of the members here has been to help you appreciate what you have. Just because you paid a low amount does not make it a junker or beater. Man, I wish I would have bought more K98s when I was getting them for $125 same goes for the rest of my collection. Others will tell you the same. I made the mistake of messing with one of my milsurps when I was young and dumb, I regret it. Now I try to restore them when I can pick them up cheap. You are still "free" enough in this country to do what you choose with your property.
As promised, I will show you how I got a scope on mine. Let me start by saying this is not the best way. It is cheap, easy and effective. It has never fallen off or came loose.
First here is an overall shot. I am leaving the pics big so you can study them.
Mine is a 1980 dated one. I used a Chinese Red Star 4x20 Scope I got back in the early 90s. It has a three post reticle and reminds me of shooting my PU sniper. The rings are a cheap set of Chinese aluminum ones.
Now the how I did it. Going slowly is the key. Check fit, file and check, over and over. Because they were aluminum a regular metal file will do. Maybe a dremmel but you can remove too much to fast. The idea is to remove enough from the slanted side of the ring to get the clamp to tighten on the smaller rail. You might also have to contour the "biting" area to fit into the rail. That's about it. Things to keep in mind are the bolt throw, so it does not hit the scope or rings and the ejection pattern.
As to where to find these rings, I don't think they were even $15. I would try gun shows, amazon, ebay, maybe airsoft suppliers, or any other place that sells cheap Chinese parts and accessories. You might be able to adapt another style of rings, this is just what I did. If you can find rings that the tightening screw can be completely removed they will work best to get a straight surface.
I can tell you set up like this I can out shoot my friends sporting .22 and can make hits easily out to at least 100 yards.
If you absolutely can not find any, I can dig in my parts bins and see if I have some that will work. I hope this gives you some ideas to help you out.
