Detailed Features 

 
The Kick-Off system is a hydraulic stock absorber that sits between the receiver and the butt pad. It noticeably reduces felt recoil on heavy 3-inch loads, which matters during long shooting sessions or for shooters who are recoil-sensitive. The gas-operated action also handles a wide range of light target loads through heavy hunting loads without adjustment. 
 
At 6.76 lbs, the A400 Xtreme Plus is lighter than most comparably equipped 12-gauges, which helps with carry weight in the field. The Realtree Max-7 camo pattern was designed specifically for wetland environments. It has the blue-gray and brown tones that break up a silhouette against water and flooded timber. 
 
The chrome-plated trigger provides a consistent pull and resists corrosion in wet conditions. The bead sight is minimal but adequate for wing shooting.

The A400 Xtreme Plus earns strong reviews from waterfowl hunters who run it hard in wet conditions. The Kick-Off system gets specific praise from hunters who shoot heavy steel loads all day. The difference in cumulative recoil fatigue is meaningful by afternoon. Reliability across a wide range of load types is consistently highlighted as a reason to choose this gun over others at the same price.

Common criticisms include the 2+1 capacity (limited for some applications), weight distribution that some shooters find muzzle-heavy, and price. A few long-session users say the gun still feels heavier than they'd prefer after extended field use, despite the lighter weight on paper. Aftermarket customization options get discussed positively. The Optima-Choke HP system is widely compatible.
