Eightbore,
At my request Adam of CSMC made me a lighter 32" RBL 12 than my 9lb 3oz RBL which has a PG, BTFE, and vent rib.
- Oh, the vent rib popped loose so I sent the gun back to Adam for repair. He returned it within a couple weeks and it had an assisted opener installed! With the opener the gun weighs 9lbs 4oz.
My companion 32" RBL 12 weighs 7lbs 9oz. It is a SG and BTFE.
The barrels from my light RBL 12 fit the heavier receiver perfectly with but one exception. The firing pins and breach balls are much wider on the heavier receiver.
The barrels of the heavier are obviously much thicker at the breach/chamber area.
