I have put together about 7-8 AR-15's in the past. The most recent AR/.223 build I had a problem while installing the barrel.
After I had finished putting everything together, the bolt did not line up with the bbl ext correctly. It seemed like it was off just enough to hold the bolt up from closing. I have never had this problem before.
I loosened everything up and it seemed to go in perfect but as soon as you tighten the barrel nut up it turns very little, like I said just enough to hold it up.(counterclockwise if you were looking at it thru the upper reciever.)
What the hell is causing this to happen?
-The barrel is a brand new.223 Wylde Chamber/ 18" WOA w/ Stag arms M4 ramp ext/Mid gas
-Bran new BCM Upper reciever
-Larue 13.2" Handgaurd
