Mossberg's 930 Pro-Series Sporting features premium coatings and finishing for reliability and increased performance to stand up to the rigors of competition. This handsomely-appointed, semi-automatic shotgun gives clays shooters the competitive edge. The 930 Pro-Series Sporting was designed in collaboration with Gil Ash and Vicki Ash, professional shooting instructors at the renowned OSP School, and Shotgunning editors for Safari Magazine.

The beveled loading gate and extra, friction-reducing finish on the shell stop, bolt slide, and elevator facilitates quick and easy reloads in the heat of competition. The special sporting clays stock is designed to fit correctly right out of the box, and its Stock Drop System provides five drop-at-comb adjustments to further perfect fit for any shooter. The HiViz TriComp sight utilizes interchangeable LitePipes, in three colors and three shapes of varied height, for superior sighting for any competitive environment.This 930 Pro-Series model has a walnut stock and forend with a blued, 28" vent rib barrel and Cerakoted receiver with a 4+1 capacity. It includes a set of Briley chokes (Skeet, Improved Cylinder and Modified) with a carrying case.
