Thanks, I'll try to switch them out.
But how about this;
a friend-co worker has a Benelli SBE 2, with a 28 inch smooth bore barrel. I bought him a slug barrel for the same SBE 2, and the forearm piece no longer worked so we had to track down the right forearm when he switched to slug barrel shooting.
I would have assumed that these were interchangeable too, without any other parts being needed, but that was not the case.
Thanks for the help.
