The Mossberg 590 Shockwave Shock’n Saw in 12 gauge (brand part no. 50647) is a pump-action firearm built around a 14.375-inch barrel with a 3-inch chamber, combining the Shockwave’s Raptor bird’s-head grip with a signature top-mounted carry handle. Mossberg finishes the Shock’n Saw in black with a blued barrel and equips it with an ambidextrous top-tang safety. Because it ships without a shoulder stock and with a barrel under 18 inches, the Shock’n Saw is classified by the ATF as a firearm rather than a shotgun; no NFA paperwork or tax stamp is required, only a standard FFL transfer. Among pump-action shotguns in the pump-action shotguns category, the Shock’n Saw favors shooters who want the Shockwave’s compact profile with an integrated top handle.
