The Beretta A300 Ultima Custom is a 12-gauge gas-operated semi-automatic shotgun with a 28-inch smoothbore barrel, 3-inch chamber, and 3-round capacity. It weighs 7.62 lbs and comes with an adjustable choke, single bead sight, RMR-compatible optic mount, and a custom finish.
The gas-operated piston system bleeds gas to cycle the action, which softens felt recoil compared to inertia-driven designs, useful for high-volume shooting. The adjustable choke lets you tighten or open the pattern depending on the target distance and shot size. The RMR mount is built into the receiver, so adding a red dot doesn't require drilling or adapter plates. At 7.62 lbs with a 28-inch barrel, the balance leans forward, which suits a swinging shooting style for bird hunting.
The custom finish differentiates this from standard A300 production guns.
The Beretta A300 Ultima Custom gets strong marks for reliability. Beretta's gas-operated platform has a long track record, and this configuration continues that. Users appreciate the RMR mount and adjustable choke as practical upgrades rather than gimmicks; the flexibility to run different choke tubes and add a red dot covers a wide range of use cases.
Handling and ergonomics draw consistent positive feedback. The balance and feel during extended sessions come up often as reasons people choose this over competing gas guns. With the RMR, shooters report meaningful accuracy improvements at varying distances, though users new to red dots on shotguns mention it takes some adjustment time.
The main criticisms are weight and price. At 7.62 lbs, it's on the heavier end for a field gun, and buyers who spend long days walking mention fatigue. The price sits above the standard A300, which draws comparisons to other premium gas-operated options. Maintenance is what you'd expect from a gas system, more components to clean than an inertia gun, which comes up occasionally in reviews.
