This Super X4 follows on the heels of the most successful Winchester autoloader ever: the Super X3 Black Shadow. There would be no point in the new SX4 if it did not take function, handling, and egonomics to the next level. And it does. This SX4 is a dedicated hunting machine with its all-black exterior that is non-glare to prevent spooking game. Critical functional controls are more abundant and more comfortable to operate, which is a real benefit in damp weather and cold conditions. Quadra-vent ports release excess gas for cleaner operation and cycles out of the box regardless of shell size or load.
