I don't want to tarnish the finish on the barrel but yes, carefully trying this might be a good option, I have good mechanics hands to pull it off safely. Might try a real hot heat gun first.
I'd like to try that but just nothing to get ahold of it has to be a press from the other side. I may try flipping this last component when I get it out to be able to use a small slide hammer and a hook in the future.
I have a Bull Barrel 10/12 I had built by the Special Ops. Shop in Madisonville Tn. back in 1998 and I have the suppressor end all apart now except for the first component diffuser that goes in as you put it back together. This is all stainless components and I have it all cleaned back to new...
