The 940 JM Pro is Mossberg’s Jerry Miculek-signature competition shotgun, now cut for Shield RMSc-pattern micro dots. A redesigned gas system, oversized loading port and adjustable stock are built for quad-loading and fast stages. HIVIZ fiber-optic front sight stays useful until you mount a red dot. Briley choke tubes let you tune the pattern for the game or the stage.
