i like the lowers. the lowers were a blem and a bare lower. they have set screws for the bolt release and for the take down pin. i might look around for another blem if i can find them cheap enough. i bought the blem from Schuyler Arms (http://www.schuylerarmsco.com/) and on the arfcom EE. the uppers and lowers fit pretty good. i haven't installed the pins, so i can't say for sure, but they seem like a pretty good fit.
Let me know if you find some. If I have the cash I would split the shipping with you and rent your jig if your willing!Sent from my VS985 4G using Tapatalk
