Looking to build an ar-15 from the ground up. And I mean completely. I want to build the lower, upper, all of it. I have to knowledge on how to build one, but does anyone have a very detailed parts list? Another thing, I may go with 5.56/.223, but there are so many possibilities I may want to change it up a little. But I need to do my best to stay UNDER 1250. So not 1275 or 1300, 1250, I've already stretched it that far. Any tips anyone might throw in for the build? Thanks
