What our reviewers liked and didn't

- Integrated cantilever scope mount provides a stable optics platform
- Gas-operated system significantly reduces felt recoil from heavy slug loads

- Good practical accuracy for typical deer hunting ranges
- Durable, weather-resistant synthetic construction
- Excellent value for a dedicated semi-auto slug shotgun
- Not easily convertible for wingshooting or clays due to the dedicated slug barrel and mount
- Smoothbore design means less precision than a rifled barrel slug gun (though often sufficient)

- Consistently accurate with a variety of slug types
- Reliable cycling, even with heavy loads
- Durable, weather-resistant synthetic stock and finish
