BCH is right. I started this to hunt with an AR15 in PA.
I figured the game warden would have trouble citing me if I showed an open gas port.
Now when I get a new barrel I just attach it with a nut, add a scope and shoot.
I have been writing down my scope settings for easier returnability to zero as I switch between uppers.
I will add a schedule 40 handguard and reload some cases fired in the same chamber to shoot more when the winter ends.
I have been writing the barrel I used on each box of brass ammo I fire to keep them separated for better chamber fit.
I have found that more tapered cases seem easier to eject.
