I saw one at a shop and bought it out of curiosity. It's a high rib barrel and a field receiver with a rib extension secured on top. You can see just a hint of the grooves for the field receiver under the trap rib extension. Monte Carlo stock. It is a soft shooter. I like the left side loading port but you have to thumb the shell in right so it gets whisked up into the chamber. To me, the loading feature is not quite as smooth as the excellent Double Auto.
A guy at our club had one and he let me shoot a round with it several years ago. Even with the monte carlo stock I couldn't see anything but the back of the receiver. The comparison to the Winchester Super X1 is more like comparing apples and lemons. I'll let you guess which gun is the lemon.
