I want the most square lockup I can get for my bolts lugs. So for me I don't care if the upper cost me 20 bucks are 200 bucks I'm going to lapp the reciver face and then do a compression fit with ss shim stock and by freezing the barrel and heating the upper so when they return to normal room temp they are a very tight compression fit.
All my guns shoot.
