Designed with input from competition legend Jerry Miculek, this Mossberg 940 JM Pro is built to win. It features a race-ready gas system with nickel-boron–coated internals, optic mounting options, and competition-level ergonomics. The adjustable stock (13–14.25” LOP, with drop and cast tuning), fiber-optic sights, quick-empty magazine release, and Briley choke tubes make it both versatile and high-performance. Reliable, fast cycling with diverse loads and minimal cleaning required—this is a top-tier shotgun straight from the box.
