You need a trained Browning gunsmith
Unlikely. Browning does not sell xtra barrel sets for O/U guns that are not originally sold that way, in fact, it's difficult and expensive to get a replacement should you damage one. However, if you were lucky enough to find an XT unsingle barrel in inventory somewhere it would have to be fit by a very competent gunsmith. Don't hold your breath!!
NO! The 1187 barrel was for remington shotguns,the auto-5 shotgun is a browning shotgun.
