I was looking at a used 1100 in a gun shop the other day and noticed that someone had installed a metal O-ring in place of the regular rubber barrel seal. Does anyone have any experience with metal barrel seals? Do they seal the gasses better, or are they just more resilient than rubber?
(and yes, I know the difference between the barrel seal, the piston rings, and a barrel seal activator :wink: )
