Detailed Features 

 
The walnut stock is finished with oil rather than a heavy lacquer, which preserves the wood's natural texture for a better grip surface in field conditions. The Micro-Core recoil pad noticeably softens felt recoil, which makes a real difference during long days shooting clays or birds. The crossbolt safety works with a comfortable push-button motion that doesn't require you to shift your grip. A chrome-plated trigger gives a clean, consistent pull. The ventilated rib runs the length of the barrel for heat dissipation and provides a natural sighting plane. 
 
At 6.70 lbs the shotgun is light enough to carry all day on an upland hunt without becoming a burden by afternoon. 
 

Target Audience 

Hunters who spend serious time in the field and competitive shooters who want a 20-gauge that will run reliably across thousands of rounds. Works for newer shooters who want a lighter-recoiling platform and for experienced shooters who know exactly what they want in a field gun. 
 

Usage Scenarios 

• Waterfowl and upland hunting in the 20-gauge is where this gun is most at home, especially for hunters who walk a lot of ground. 
• Clay target sports benefit from the low recoil and clean trigger. 
• Extended range sessions are manageable at this weight.

The A400 Xplor Action 20-gauge gets generally positive reviews. Build quality and aesthetics lead the praise — the walnut stock is consistently called out as a highlight, and the overall fit and finish is well-regarded for the category.

Recoil management is the other main positive: the gas system combined with the Micro-Core pad keeps felt recoil low even with lighter 20-gauge loads, which makes it comfortable for longer sessions. Reliability across different ammunition types gets good marks — most users report smooth cycling without jams or malfunctions.

The 20-gauge caliber draws discussion in its own right: most buyers like the lighter recoil and find it adequate for small game and clays, though some coming from 12-gauge feel the trade-off in pattern density. Weight is occasionally noted as slightly higher than some competing models, but most accept this as a byproduct of the build quality. Price comparisons appear, with some buyers feeling the cost is justified and others finding comparable options at lower price points. The shotgun also has a short learning curve for semi-auto newcomers, which gets mentioned by a few users transitioning from pump or break-action guns.
