This is my first post on THR, so I apologize in advance if I'm missing something obvious here. The Situation: I want to buy a scope for a CZ-527 in 7.62x39 caliber. I've looked this up online and even saw a previous thread from THR, but it looks like a lot of people ended up buying rings or scopes over and over because they didn't fit or weren't able to get the bolt to clear the scope. Money is tight and I want to try to avoid this. I'd just go to a gun shop in person but they're flooded with people now. I'm also kind of new to scopes on traditional rifles. When I was in the Army we had optics, but every weapon I have with a scope has either picatinny rail. I also prefer irons, but I'm going deer hunting and a scope is probably going to be better suited from where I'm going to be shooting from. The Question: 1. What size rings should I get? I keep hearing Warne medium, but there's different sizes of that (Warne medium 1 inch / Warne medium 30mm). 2. Does the scope have to match the rings? Will the scope have information about what size rings it will fit? 3. What magnification should I be looking for at 7.62x39mm range? It looks like that bullet experience significant drop at about 200 meters, and I probably wouldn't take a shot beyond that. 4. How do I know if a scope is going to be good? Maybe this is a stupid question but, if the range doesn't have to be that far, I don't see a problem with getting a $50 scope with minimal magnification. It's just suspiciously cheap.
