I had a friend tell me that he didn't like the Weaver strap style rings because they were extremely hard on scopes. I never thought much of it because in all honesty I hate them too. However, I need some rings to mount a scope in and I have a set of these in a box that I took off of an old gun. Now that I'm needing a set of rings, I'm thinking of mounting these. The reason I didn't like them was that it's hard to get the crosshairs aligned since the scope tends to turn when you tighten them down, but I'm thinking this is better than spending $35 on a set of scope rings for a gun that doesn't see much use. Only a few times a year. This made me wonder though, are these hard on the scope? I don't want to ruin a $300 scope by running these things? Or is my friend full of it?
