The MK II revision addressed early reliability issues by refining the gas-operated action. This example retains a bright, jeweled bolt that cycles smoothly in the polished blue alloy receiver, keeping overall weight low for comfortable carry.
A 22 inch steel barrel makes the gun quick to mount and swing, particularly in dense cover. The installed Herter's selectable choke/compensator lets the shooter adjust constriction on the fly, broadening its utility across upland and small-game scenarios.
The walnut-finished hardwood stock features cut checkering, a pistol grip, Monte Carlo comb, and a red Winchester ventilated recoil pad with white-line spacer. Length of pull measures 14 inches for a steady, consistent shoulder fit.
A brass bead front sight provides a simple, reliable aiming reference. The magazine plug limits capacity to 2+1 rounds, making the shotgun ready for migratory bird regulations while preserving the original 3-round design.
