I put a 'beater' simmons 3x9 on it to see how it looked. I used 'beater' rim-fire, 1" rings, and it looks pretty nice, eye relief feels and looks ok, I am limited to where I can mount the scope, any scope, there is very little room for movement in the rings. The dovetail that the rings clamp into is very short. I only have about a quarter inch to play with. The rings I have on it are weaver, aluminum, standard 1" rings.. base is alum. and ring is steel. If they were shorter, from front to back, I imagine I would have more room to play with. I see some scopes have the turrets further back on the tube than others... we'll see how this works out, I have to wait until mid April to shoot it, there are no decent ranges here in central Fla..
