Browning's Maxus shotgun is an unequaled reliability gas-operated autoloader. Its Power Drive Gas System is extremely reliable in all conditions, regardless of the heavy or light loads being used. The patented Speed Lock Forearm system makes taking down the Maxus for cleaning or storage fast and makes attaching or removing the sling a snap. The Maxus also has a Lightning trigger. The Sporting model has an aluminum alloy receiver and a steel barrel with vent rib. This 12 gauge model has a blued 30" barrel with Invector-Plus choke tubes, HiViz sights, matte nickel receiver with engraving, and walnut stock with checkering and high gloss.
