I am looking into a C7 clone build and would like some information on the 80% lowers. I have seen some here on the forum with the Canadian engravings done on a 80%. So who can do the finish work on the receiver and the engraving? What costs are associated with the finishing and engraving along with anodizing? I know it is just as easy to buy a A2 lower but the details and realistic look of what can be had with a 80% lower is amazing.
