<p>You don't need a gunsmith to craft a competition-worthy autoloader. With design help from legendary competitive shooter Jerry Miculek, the Mossberg® 940® JM Pro Semi-Auto Shotgun offers winning performance right out of the box. A redesigned gas system with stepped and vented spacer keeps this gun shooting reliably for 1,500 rounds before you need to clean it. Synthetic MultiCam stock adjusts for length of pull (13 to 14.25), drop, and cast to customize for the best shooting fit. The 24 vent rib barrel comes equipped with HiVIZ TriComp fiber-optic front sight for rapid, accurate aiming. Other details of this competition-grade model include updated loading port and elevator/shell-catch design, charging handle/bolt release with anodized finish, and nickel boron-coated internal components. Mossberg 940® JM Pro semi-auto shotgun includes Briley extended chokes (C, IC, M) and is AccuChoke compatible.</p> <ul> <li>Endorsed by legendary competitive shooter Jerry Miculek</li> <li>Redesigned gas system </li> <li>Stepped and vented spacer</li> <li>Adjustable length of pull (13 to 14.25), drop, and cast</li> <li>24 vent rib barrel </li> <li>HiVIZ TriComp fiber-optic front sight </li> <li>Updated loading port and elevator/shell-catch design</li> <li>Charging handle/bolt release with anodized finish </li> <li>Nickel boron-coated internal components</li> <li>Briley extended chokes (C, IC, M) </li> </ul>
