At the Beretta booth, I saw a Beretta Tactical 1301 with a distinct optic mount. It is something new by Aridus Industries. The mount is a dedicated Aimpoint mount. It lowers the Aimpoint so that the iron sights co-witness thru the Aimpoint. It looks like the mount replaces the factory rear sight and has an integrated rear peep sight.

No word on availability or pricing.
