anyone here mill there own lowers from 80% lowers? i have been looking into this after not being able tot find a source for customs and found out today that my buddy has a milling machine in his garage. talked to him about the idea and hes going to split the cost of the jig and we will machine a couple together. right now im looking at www.tacticalmachining.com but would like to hear more ideas and see some pics from others who may have done this in the past. thanks.
