I have seen a lot of people building their own AR-15's and I want to go a different route. I want to build an AR-10, which to my under standing shoots the .308 or 7.62 round. This is going to be my long over time project so just for now I am looking at lowers. Cause most of the uppers I have seen are a thousand plus, so that will take a little time to save up for. I am thinking about a DPMS lower or a Armalite lower. Kinda cheap cause I still have to pay a $200 tax stamp. Would either one be a good starting choice or dose any one else have an opinion on what lower to start out with? Any and all input on a AR-10 build is greatly appreciated, thanks!
