I bought a new Arken scope. 6-24X50 FFP 34mm tube, zero stop, nice glass. Minimum focus is only to 25 yards, and is marked like that. I seldom take a shot below that so no problem. I really like the scope, for me this scope hit all the marks. So, I bought another exactly like it. Here's the curious part, the second scope focuses to 20 yards and is marked as such.
