The FLEX 590 Tactical is a modular system of shotguns based on the legendary model 590 with the LTS (Tool-Less Locking System). This system consists of three convenient connecting technologies that bring another level of flexibility to your tactical shooting endeavors. One locking pen is for the stock, one for the forend, and one for the recoil pad. The Tactical series is set up for any of your shotgun's personal protection needs, but easily allows you to change the stock, forend, or recoil pad for a specific need. The FLEX 590 Tactical features a black 6-position stock and tactical tri-rail forend.
