Description

If you’re a serious waterfowler who demands a shotgun that can take a beating in the blind and still deliver shot after shot, the Rob Roberts Customs Beretta A400 RR Custom Xtreme Plus 12 Gauge 28-inch is the real deal. This isn’t just another A400—it’s a custom build from Rob Roberts Custom Gun Works, tailored for the toughest duck and goose hunts. Starting with Beretta’s legendary Xtreme Plus platform, they’ve added a tactical cocking handle, a Duck Boat Drab distressed Cerakote finish, and a Steelium vent rib barrel with Optima HP choke. It’s a full-size, right-hand semi-auto that’s built to shrug off mud, water, and cold while cycling everything from 2¾-inch target loads to heavy 3½-inch magnums. Per manufacturer specs, this is a 12-gauge workhorse with a 28-inch barrel, synthetic Kick-Off stock, and aluminum receiver—ready to go straight from the case to the marsh.

Key Features

  • Steelium Vent Rib Barrel — Why it matters: This barrel uses a tri-alloy steel that patterns tighter and more consistently than standard barrels, so you get dense, even shot strings on fast-moving ducks and geese.
  • Duck Boat Drab Distressed Cerakote Finish — Why it matters: The low-glare, weathered look blends into marsh grass and cattails, and the Cerakote resists rust and corrosion from saltwater, mud, and morning dew.
  • Kick-Off Stock with Synthetic Construction — Why it matters: The built-in hydraulic recoil reduction system soaks up the kick from heavy 3½-inch loads, letting you stay on target for fast follow-up shots without flinching.
  • Tactical Cocking Handle — Why it matters: Oversized and textured, this handle gives you a positive grip even with wet, gloved hands, so you can chamber a round quickly in low light or heavy cover.
  • Optima HP Choke System — Why it matters: Designed specifically for steel shot and non-toxic loads, these chokes deliver clean patterns with no deformation, maximizing energy transfer on every bird.

Who It’s For

This shotgun is built for the southern waterfowler who spends more mornings in a layout blind than at a clay range. If you hunt flooded timber, coastal marshes, or rice fields from Arkansas to the Gulf Coast, you need a gun that cycles reliably in mud, cold, and rain. The RR Custom Xtreme Plus is also a fit for the hunter who appreciates a custom touch—a distressed finish that hides scratches, a tuned action, and a proven platform from Beretta. It’s not a safe queen; it’s a tool for the blind.

Pros & Cons

  • Pro: Rock-solid reliability with a wide range of 12-gauge loads, from 1-ounce target shells to 3½-inch magnums.
  • Pro: Custom Cerakote finish is both functional and good-looking, with a low-glare, distressed appearance that hides wear.
  • Pro: Kick-Off stock reduces felt recoil significantly, making it comfortable to shoot heavy loads all day.
  • Con: The 28-inch barrel is ideal for waterfowl but may feel a bit long for upland or close-cover hunting; a 26-inch option would be welcome for those who want one gun for everything.

FAQ

What loads does this shotgun cycle reliably?

Per Rob Roberts Customs specs, this A400 cycles 2¾-inch target loads (1 oz and up), 3-inch field loads, and 3½-inch magnum waterfowl loads without adjustment. The self-cleaning gas piston handles light and heavy shells equally well.

Is the Cerakote finish durable enough for saltwater hunting?

Yes. Cerakote is a ceramic-based coating that resists saltwater, rust, and corrosion. The distressed finish actually hides scratches and wear better than a smooth camo dip.

Does it come with choke tubes?

Yes. It includes three Optima HP chokes: full, modified, and improved cylinder. These are designed for steel shot and non-toxic loads, per Beretta’s specs.

Can a left-handed shooter use this right-hand model?

This model is configured for right-hand shooters (right-hand ejection and bolt). Left-handed shooters would need to look for a left-hand version or an ambidextrous model.
