I am in the early stages of a 6mm ARC build. It has been quite some time since I built one from scratch. I am doing this because I wanted to build a left handed 6mm ARC. I have acquired the AERO precision lower, a lefty STAG upper and BCG for 6mm ARC, and I just placed the order for a faxon gunner barrel. I am not exactly seeing this rifle as being a "budget build" so I am looking at the "premium" parts.

I am looking at buffers and AERO has an enhanced buffer tube that is OD green that I like. Will this work on my standard mil-spec lower? I am just curious since their are enhanced uppers and the like, I dont want to waste time and money if this wont work on my lower. From what i have read it will work but I want to make sure
