Mossberg's 590R is a 12-gauge pump with a 3-inch chamber, an 18.5-inch barrel under an integrated heat shield, and 6+1 capacity. The receiver carries a Picatinny rail with Magpul MBUS 3 flip-up sights, and the five-position stock with MOE pistol grip adjusts from 12.5 to 16 inches of pull. Overall length is 37.5 inches, weight 7.75 pounds, finish matte. The safety is an ambidextrous AR-style rotary selector, the trigger is flat-faced, and twin action bars, dual extractors and an anti-jam elevator handle the cycling. The loading port is enlarged and beveled, with an exposed follower for a quick status check.
Although listed under hunting shotguns, this is a defensive configuration first. Still, a 12-gauge is legal for Texas deer under TPWD rules, and feral hogs have no closed season or bag limit, so a short, rail-equipped pump with a 3-inch chamber doubles as a ranch gun. The adjustable stock fits several family members, and the rail takes a red dot for low-light work around the house.
