Hey, I am considering picking up a pal's encore.Wondering if a scope can be mounted on a 24" encore barrel w/open sights? It has a TC peep sight on the chamber/reciever(add on?) and a standard folding rear sight near the center of the forearm. The base of the"peep sight" is only 1 3/4".Are there enough mounting screws under this to mount a weaver type base?
