If you then try to close the barrels for reassembly the bottom of the lug hits the square bolt. Both those parts are very hard steel. You would have to break the bolt or the bottom of the barrel lug to somehow close the barrel set and that ain’t gonna happen even if a sledge hammer is used. (Well never tried that but I’m guessing that’s a correct statement).

For interest there are approximately 100 parts (plus or minus a few based on vintage) in a Parker Bros hammerless shotgun. Many are fixed in place and some move to facilitate operation.

Yep that is where I was going with my first post But oh well ! Well said Jack
