Barrel Thickness & Gas Port Sizing
Over on another site there is a thread asking for the correct gas port size for a 16" barrel with a mid-length gas system.
Multiple replies mention barrel profile/OD at the gas port advising that a barrel that uses a .750" gas block would need a different size port than a barrel using a .625" gas block.
You are talking about is a .0625" difference in the length of the port. I do not see how this would make a difference.
Am I blind or are these people full of it?
