Let me see if I get this straight. You bought a rifle that has no sights on it, but in lieu of a scope you want to have sights put on it until you can save up for a scope? Well as far as I know having sights installed will cast you about as much as a scope. The barrel will have to either be drilled and tapped, or dovetailed depending on the sights you want, and you also have to figure in the cost of the sights themselves. I guess there are some sights made to be silver sodiered on but that still requires expertise and I don't know if I would trust them to stay on long. Might be cheaper just to go with an inexpensive piece of glass for now until you save up for whatever optics you want.
