The Mossberg 500 ATI Tactical is the perfect balance of time-tested Mossberg 500 reliability and the functionality of ATI components. As functional as it is fierce-looking, the Mossberg 500 ATI delivers the features that have made the 500 the pump-action of choice for millions worldwide: ambidextrous safety, dual extractors, positive steel-to-steel lockup, twin action bars, and a smooth operating anti-jam elevator. Now, Mossberg has teamed up with ATI to outfit this model with an exceptional set of components\u2014 bringing unprecedented stock, heat shield, side saddle and accessory rail options in a single coordinated package to the 500 family of tactical shotguns. The ATI TactLite 6-Position Stock provides a 3\u201d LOP range; has a Scorpion recoil-reducing rear pad and grip pad; and a 1\u201d adjustable cheek riser. Sling mounts via a QD socket on the recoil pad.<\/p>\n<p>The ATI Halo Heatshield is a free-float design with front\/rear blocks and silicone pads, that provide no metal-to-metal contact with the barrel. A front dovetail rail attachment comes with two 2\u201d rails for accessory mounting convenience. A shield-mounted post front sight provides clear sighting. The ATI Halo Side Saddle is mounted directly to the 500 shotgun\u2019s tapped receiver. Three Add-A-Shell units are included, that mount to any of 9 possible positions. Each Add-A-Shell unit can be flipped 180\u00b0 for user-preference of brass up\/brass down orientation. A removable top rail provides for a variety of sight or accessory mounting options.
