Affordable, solid, but be wary of overtight mount screws - Leapers UTG ACCU-SYNC 30mm High Profile 50mm Offset Picatinny Ring

Overall I rather like this scope mount. It provides a fairly lightweight, solid, and pretty slim mounting option for a 30mm scope.
My only issue was with the mount screws.
I tend to swap optics around as I experiment with different builds, and while the instructions for this base say the mounting screws have a top torque of about 35in/lbs, I would say stick closer to 20-25in/lbs.

Otherwise, the screws bind up so tight as to almost be permanently attached. I just about broke the heads off several of my torx bits trying to get this thing loose.
Just be aware of that, and this mount should serve you well.
