Description

Beretta A400 Xtreme Plus LH 12 Gauge OD Overview
The A400 Xtreme Plus is built for the worst conditions waterfowlers face. Its B-Link gas system cycles fast and stays clean, handling everything from light 2 3/4 inch loads to heavy 3 1/2 inch magnums without adjustment. This left hand model mirrors the controls and ejection for lefties, so spent shells eject away from your face. Beretta’s Kick-Off hydraulic recoil reduction system in the stock dramatically softens recoil from big magnum loads, helping you stay on target for follow up shots.
The 28 inch barrel has a vent rib, a fiber optic front sight with a steel mid-bead and Optima-Bore HP technology, and five extended Optima HP chokes are included. 5 inch overall length. A 2 position crossbolt safety completes the package.
Built for Left Handed Hunters
Left handed hunters often settle for right hand shotguns that eject toward their face. The left hand A400 Xtreme Plus puts the ejection port and controls where lefties need them for faster, more comfortable shooting.

Kick-Off Recoil Reduction
The Kick-Off system uses hydraulic dampers in the stock to absorb recoil, which can reduce felt recoil significantly with heavy 3 1/2 inch steel loads. Less recoil means less fatigue and better shooting over a long day in the blind.
Care in the Field
Rinse mud and salt water off after each hunt, dry the action and lightly oil metal parts. The B-Link system is easy to clean, and the synthetic stock needs only a quick wipe down.

Choosing Shells
Pattern your shotgun with several loads at the distances you expect to shoot, since every barrel and choke combination behaves differently. Use the right shot size for your game or target and follow local rules on nontoxic shot where required.
Fit and Mounting
A shotgun that fits lets you look straight down the rib with your cheek firmly on the stock. Practice smooth gun mounts at home with an unloaded gun to build consistency in the field and on the clay range.
Care and Maintenance
Clean the bore, chokes and action after each outing, especially after rain or salt water. A light coat of oil on metal parts and a clean action keep the shotgun running reliably for years.
Choke Selection
Tighter chokes such as modified and full extend effective range for waterfowl and turkey, while improved cylinder and skeet chokes open patterns for close birds and clay targets. Always use chokes rated for the shot you are shooting, especially steel.
Recommended Accessories
Eye and ear protection, a cleaning kit, extra choke tubes and a padded case are smart additions. Hunters may want a sling, while clay shooters often add a shell pouch and recoil reducing pad.
