I have a semi auto 12 ga, revelation brand shotgun that is stamped ( brescis italy, )(thats exactly how stamped not a misprint)
that has performed flawlessly for over 20 years, that shotgun is one of my favorite guns and I would love to add a 2 or 3 shot ,
12 ga magazine extension to,
I don,t know who sells any extension or what other brand of magazine extension might be interchangeable,, thus that might be used?this appears to be a very well designed inertia driven action, similar to Benelli or H&K
any help would be appreciated
