Ok...I have done the 80% Ar Lower with good results. I was not too concerned about messing things up because the upper was from a reputable manufacturer and that is where all the high pressure stuff is.
With the 80% polymer handgun build how critical are the milling issues with it. I keep picturing myself with a slide flying off when I test fire it.
Are there concerns here?
