The Mossberg 590 Shockwave saddle mount configuration is a compact 12 gauge pump-action firearm that adds a saddle mount to the standard blued Shockwave (brand part no. 50648). Mossberg builds it on the 590 action with a 14.375-inch barrel, and the Shockwave’s Raptor bird’s-head grip takes the place of a shoulder stock. The ambidextrous top-tang safety and bead sight keep the controls simple. It carries 5+1 rounds and comes with a cylinder bore choke for close-range patterns. Choose this version if you want the saddle mount on the receiver from the start.
