Peeps, either receiver or barrel-mounted, may be your solution, but do what you have to in order to make killing shots, your first obligation. Something like a 1 or 1.5x to 4 or 5x should be plenty, and those scopes are usually light and compact if you stay away from tactical stuff. The Leupold 2.5 is tiny and light, only 6.5oz, with almost 5" of ER.
