Mossberg 590S Magpul 12 GA 18.5" 9rd Holosun HS407K Shotgun

The 590S Magpul combo is a 12 gauge pump that comes with a Holosun HS407K micro dot already mounted on the optic ready receiver. The big trick of the 590S is that it cycles 1.75", 2.75" and 3" shells interchangeably, with no mini shell adapter, so you can mix lengths in the same tube. Capacity depends on what you load: nine 1.75" mini shells, six 2.75" shells or five 3" shells in the magazine, plus one in the chamber.

The 18.5" matte blued barrel has a Cylinder Bore choke and a bead front sight that sits under the dot. Furniture is Magpul in gray: an SGA adjustable stock with spacers for a 12.25" to 14.25" length of pull, and an MOE forend. The redesigned elevator and bolt slide plus an energy absorbing bumper make the mixed shell feeding work, while the classic Mossberg features stay: dual extractors, twin action bars, steel to steel lockup, top tang ambidextrous safety and a clean out magazine tube with cap. Weight is about 6.75 lbs and overall length is 38".
