Why is my barrel such a pain in the ass to re-install? I didn't realize it was so different from other barrels/uppers. It took a barrel vise to remove it. I'm having a world of trouble getting the upper to align with the front sight post.  What was the reason for it's design? (theaded barrel with no index stud) |
