[QUOTE="Urban_Hunter, post: 5776373, member: 12353"] I had the exact same problem with a BCA 16” 300BO upper. The port in the barrel is undersized IMO, and I was going to match it to the gas block port. When I pulled the gas block I realized that from the factory the ports weren’t lined up, the block wasnt seated against the ridge on the barrel, blocking about 30% of the gas off. I went ahead and bored it anyways and haven’t had a ftc since [/QUOTE]
