Mossberg 590A1 (51660)
The Mossberg 590A1 (51660) is a 12-gauge, pump-action shotgun built to the same MIL-SPEC 3443G standard that put the 590A1 in the hands of U.S. military and law enforcement units for decades. It pairs a 20-inch heavy-walled barrel and 3-inch chamber with an 8+1 round magazine tube, Parkerized finish, metal trigger guard, and metal safety button. The full-length synthetic stock, twin action bars, and ambidextrous top-tang safety give it the handling shooters expect from the 590 platform. It's a serious choice for home defense, duty use, and shooters who want a fighting shotgun without modification.
