Like the original Super X®3, the Super X®4 uses the proven ACTIVE VALVE GAS SYSTEM that automatically self-adjusts to allocate the exact gas pressure necessary to reliably cycle a wide range of loads commonly used for hunting or target shooting. When firing the heaviest magnum loads in 3 1/2" models, gases vent upward and a portion of them are vented forward out the Quadra-Vent ports in the forearm to help regulate bolt speed. Both 3" and 3 1/2" Super X4 shotguns will reliably cycle even 1 1/8 oz., 2 3/4" light loads. Excess gases from heavy loads are channeled through the forward QUADRA-VENT™ ports for cleaner and more reliable operation.
LOAD DIVERSITY means a Super X®4 can reliably shoot them all, from light factory field shells to heavy magnum waterfowl and turkey loads. That’s why the proven Active Valve on the Super X4 makes it the most versatile autoloader on the range, in the marsh and in the field.
