I was looking at the Beretta site and they show a mount that is supposed to fit the A400 Xtreme, A391 Xtrema, A304 and A303 Beretta shotguns but it looks like it fits to some type of dovetail in the receiver which my A303 doesn't have. Has anyone used this mount and if so how does it attach. Here's a link to the mount h ttp://www.berettausa.com/en-us/beretta-scope-base-for-semiauto-shotguns-black/c61275/
