Key Features
- Enlarged Controls — The bolt handle, bolt release, and safety are all oversized, making gloved-hand operation easy in cold weather or heavy cover.
- Wider Stepped Rib with Fiber Optic Front — The 10mm stepped rib reduces glare and helps you keep your head down, while the fiber optic front and mid-bead speed up target alignment on crossing birds or clays.
- Kick-Off Recoil Reduction System — Beretta’s hydraulic damper in the stock cuts perceived recoil by up to 40%, so you stay on target for fast follow-up shots.
- Mobilchoke System — Comes with IC, M, and F tubes, letting you fine-tune patterns for different loads or game without buying extra chokes.
- Mossy Oak Bottomland Camo — The synthetic stock and forend are dipped in Bottomland, a proven pattern for marshes, fields, and timber.
Who It’s For
This shotgun fits the upland hunter who wants a light, fast-handling 20 gauge for pheasants, quail, or woodcock. It’s also a solid pick for the skeet or sporting clays shooter who prefers a 20 bore for longer sessions without shoulder fatigue. The Kick-Off system makes it a great choice for youth or smaller-framed shooters moving up from a 28 gauge or .410.
Pros & Cons
- Pros: Reliable Beretta gas system; noticeably reduced recoil; easy-to-use controls; versatile choke set; camo finish holds up to field abuse.
- Cons: The Kick-Off system adds about 4 ounces to the stock weight, which some may notice on long walks. The 28-inch barrel can feel a little long in tight brush compared to a 26-inch option.

The Beretta’s Kick-Off system gives it a clear edge in recoil management, but the Mossberg and Winchester are lighter on the wallet. If you want the smoothest cycling and best recoil mitigation, the A300 Ultima justifies its price.
FAQ
What chokes come with the Beretta A300 Ultima 20 gauge?
The shotgun includes three Mobilchoke tubes: Improved Cylinder, Modified, and Full. These cover most hunting and sporting needs right out of the box.
Is the Kick-Off system removable?
Yes, the Kick-Off hydraulic unit is built into the stock but can be removed by a qualified gunsmith if you prefer a lighter stock. Per Beretta specs, removing it reduces weight by about 3.5 ounces but increases felt recoil.
Can I shoot steel shot through the A300 Ultima?
Yes. The Mobilchoke tubes are rated for steel shot, but Beretta recommends using a choke constriction no tighter than Modified (0.010 inch) for steel loads to avoid barrel damage. For non-toxic shot, stick with IC or Modified.
Does the A300 Ultima come with a hard case?
No, it ships in a cardboard box with a soft bag. The box includes the shotgun, three choke tubes, a choke wrench, and the manual.
