Beretta's A300 Ultima in 20 gauge is a semi-automatic field shotgun with a 28-inch vent-rib barrel, a removable choke and a chamber that accepts both 2 3/4 and 3-inch shells. The front sight is fiber optic, the metal is matte black and the black synthetic stock and forend include Beretta's Kick-Off device, with a 14.25-inch length of pull. The supplier lists it as new, SKU NGZ957.
For Illinois, a 20 gauge with a 3-inch chamber and a screw-in choke covers a lot of ground: field work with the vent rib and fiber-optic bead, and, loaded with slugs, the firearm deer seasons, since shotguns with slugs are a legal deer gun in the state. Those seasons run November 20 to 22 and December 3 to 6, 2026, with permits issued by county quota through the IDNR lottery and leftovers released after the draws. The Kick-Off device in the stock is aimed at shooters who want less felt recoil over a long day.
