It's good to see that someone else is shooting a McGowen barrel. I'm interested in how yours shoots. I have no complaints on the one they did for me. I assume the barrel you have is a 6.5BPC correct? My 20" RLGS needed to be opened up to .093 (3/32 drill bit) to function properly. When it came from McGowen the port hole was way small (.062) Best thing I found to do is oil up the bolt carrier real good and make sure your gas assembly is installed correctly. Add one round into your chamber and put in a empty magazine into your mag well. After you shoot off your round the bolt should lock back behind the magazine. If the bolt doesn't lock back you could be undergassed. (gas port to small)
Don't mean to alarm you because when you get your AR together and it shoots fine, then your good to go. But if your bolt doesn't lock back behind the empty mag, just remember that you MIGHT just have to open up the gas port a bit. Like another poster stated "you never know until you shoot it".
