Detailed Features 

 
The semi-automatic action handles follow-up shots without manual cycling, which matters in both defensive and competition contexts. The fiber optic front sight gives you a usable sight picture in low light, and the adjustable rear lets you set your zero. The included choke set covers most use cases from tight to open patterns, so you're not limited to one shot pattern for hunting or sport use. 
 
Polymer stock with pistol grip keeps weight at 7.05 lbs. At 39.37 inches overall with an 18.5-inch barrel, it's a compact configuration for a 12-gauge semi-auto.

The X4 Elite is positioned as an entry-level to mid-range shotgun, and user feedback reflects that accurately.

Affordability is the top positive — buyers who want a functional semi-auto 12-gauge without spending on Beretta or Mossberg Autoloader money tend to be satisfied. The gas-operated action cycles smoothly with standard loads, and the fiber optic sights get favorable mentions for practical usability.

The recurring negatives are build quality concerns relative to premium brands, and reliability with certain ammunition. Some owners report inconsistent cycling with light or budget loads — a common gas-operated shotgun issue that often clears up with recommended shell weights. A few users also flag that it's heavier than expected at 7.05 lbs when loaded.

This gun appeals to new shotgun buyers and those shopping on a budget. Experienced shooters comparing it side-by-side with top-tier options are generally the ones with complaints. For what it is and what it costs, most owners consider it a reasonable value.
