I want to install a set of rifle sights on my topper, preferably on top of the receiver to give a longer sight radius. Being as how I only paid $75 for the gun, I don't want to pay a gunsmith to install sights. What is the best way to do? I assume epoxy them on (at least on the receiver end) any preference on type of epoxy? How do I get the correct height? Best way to keep them in straight line and directly on top?
