Let's review the legality of adding a mag extension to a Benelli shotgun...
A while back there was a thread discussing Federal Law 922R ( I believe that's the number ) and how it applies to adding an extension tube to a Benelli shotgun.
The thought was that since the Benelli is an imported shotgun, that adding a mag extension would put it in violation of the law. However, it seems, that if you add the extension, and two other US made parts, it would comply with the law. But.....
You can buy mag extensions of all kinds for the Benelli shotguns and no retailer I've seen so far so much as even mentions the possible violation of 922R. So I thought maybe the conflict was with the M4 because of the pistol grip, but the same situation exists for the M4 - lot's of sellers of mag extensions but no mention of the possible violation of the law.
Thoughts???
