Okay, so what gives with the rubber sleeve that I assume is supposed to go over the Mercury cylinder? For the life of me, I can't get this thing on. I wish Benelli would go with Springfield Armory's "loaded" concept. This way I wouldn't have to be battling getting this thing in my shotgun. I haven't shot my new shotgun yet, but from everything I've seen & read, recoil can be a bear in these shotguns.
