I'm looking for about a 2.5x fixed scope for my Marlin 336 SS. I've read briefly about the Leupold FXII Scout, which allows a mounting forward of the receiver. Is this a preferred location? Is it the only location this Leupold will work on? I think I'd like mine further back. Anything else I should be looking at? Purely for vanity, I'd like one to match the stainless. But mostly, I'd like one that sits low on the gun, is light, fixed power, and with a good field of view. Thank you for any thoughts.
