I have a QC 10 lower with other parts I purchased from several different places. I have a RWextreme barrel I had a local guy do bolt carrier mods and assembled myself. I never got the gun to cycle reliably always having bolt closing issues. Until this week I sent the barrel to Rudy at Macon armory. This guy is Top Notch He addresses some issues with the bore not being concentric to the outside of the barrel. (something you wouldn't expect on a $300.00 barrel) He also cut a different feed cone on the barrel and gave me a new gas block that seals better than the original one supplied by RWextreme. If anyone is having issues with a 10mm build or wants to invest in one Rudy is the guy.
