I just bought a new GBL this week. It did not have any obvious flaws, but when I took it apart to clean the interior parts I ran into a problem. There were none of the metal shavings that have been mentioned in other threads, but I couldn't get it back together! I spent over 2 hours trying to get the hammer screw back in place. The screw hole on the left ear of the trigger plate was just a little off. After I finally figured that out I was able to open it up a touch with a round file. No more problems. The gun looks good and feeds my handloads with no difficulty. I think I'm going to really like this gun.
