The A300 Ultima Turkey’s gas-operated system uses an exhaust valve and a falling-block bolt lockup, delivering smooth cycling with 20 gauge 3 in shells. The reversible safety supports left- or right-handed use, and capacity is 2+1 with the plug installed.
Controls are enlarged for easy manipulation, including an extended bolt handle and an enlarged bolt-release. The stock is polymer and includes Beretta’s Kick-Off recoil reduction system, an elastomer cheek insert, molded checkering, a recoil pad, and a rear sling swivel stud. Length of pull is 14.0 in and can be fine-tuned with the included spacers/shims.
The 24 in steel barrel has a vent, stepped rib with a red fiber-optic front bead for a clear sight picture. The barrel and receiver wear the Mossy Oak Bottomland finish, and the platform is Mobilchoke-compatible for pattern tuning.
