Howdy, folks. I've been shooting my AR556 with irons for a while now, and I'm ready to see how we'll do with a scope. I have a Leopold VX-1 that I'm going to mount. It's a 2-7X32. What would be a good set of rings? I don't want to mount it higher than I have to, but am concerned about the front sight being in the way. Thoughts? Thanks!
