So, I found my Williams receiver sight for my Marlin, but the front sight is too low, so it needs to be replaced. My gun has no sight ramp, just a standard 3/8" dovetail cut in the barrel. I kind of want to find a hooded (globe) front sight to install, but after a brief search of the usual suspects on the Internet, I cannot find a dealer who carries these things. Any suggestions where to look?
