I'm looking for a fixed power scope 2x or 4x for a Marlin guide gun 1895gs in 45-70 gov. I don't want to spend more than $175 out the door for it. Any suggestions on brands and models that I should look at?

Also I'd like to have a two piece scope mount but leupold doesn't make a two piece for the Marlin guide gun. What other companies out there make a quality set of mounts and rings?

Thanks

Tom
