So I'm researching an affordable AR build. I want to build not buy a package. Note I said affordable not cheap. I want a rifle that is reliable but I have not interest in brand. I have been looking into the polymer lowers. New Frontier makes from what I can see in reviews and looking through the specs the best option in that arena. I have found a few aluminum lowers both complete and striped pretty cheap but the polymer really is appealing. Weight, price, and from what I have read it seems to hold up the same as their more main stream counter parts. So all u AR guys what say you
