Re: 6BR is Siff in Rapid Fire
While you are swapping pins, carefully inspect the camming surface on the bolt. I have had issues with the bearing surface of the pin or striker, wearing a trough in the camming area leaving a slight burr the whole length. It is fricken amazing how much binding is created in this situation.
I have had about three bolts show this and had to polish out this area to fix. Most of these bolts did not have factory pins and springs, but speedlock advertized setups and heavier springs.
