RE: peep sights
I tried a fiber optic peep from williams (a little to fine again hard to see)
I like the one t/c has a little thicker red front bead and remember to redrill the factory peep I think it was 1/64 drill bit bringing the hole to .090
I also find mounting a little high on the tang really helps otherwise using the back tang screw gives me a problem trying too pick up the front bead and no need to dig your check into the stock when the peep is forward on the tang.
