Mossberg 500 ATI Scorpion Tactical 12 Gauge Flat Dark Earth (FDE) Pistol Grip Shotgun


In stock


Mossberg has teamed with ATI, the worldwide leader in firearm stocks, forends and accessories, to introduce a highly-specialized factory version of its venerable pump-action – the Mossberg 500 ATI Scorpion. This sleeklooking, multi-functional shotgun combines all of the time-tested features of the 500 pump-action shotgun with the ATI T2 TactLite® 6-Position Adjustable Stock, featuring Scorpion® recoil-reducing rubber grip and rear pad; ATI Halo® Heatshield; and ATI Halo Side Saddle.

The legendary 500 pump-action platform is designed for smooth, reliable operation and features non-binding twin action bars; positive steel-to-steel lock-up; an anti-jam elevator; and dual extractors. Its lightweight, anodized aluminum receiver provides for added durability and better balance. And for ease of operation, the 500 ATI Scorpion has Mossberg’s universally-recognized, ambidextrous top-mounted safety.

The addition of ATI tactical accessories takes this 500 to the next level of functionality. The TactLite 6-position adjustable stock features an elongated design to improve fit for most users; a 3 7/8-inch length-of-pull (LOP) range of adjustment; and one-inch adjustable cheek riser. The stock also has ATI’s TrakLOCK® System which eliminates horizontal and vertical movement of the stock on the buffer tube and provides for smooth, secure stock adjustments. Incorporated into the stock is the Scorpion Recoil System, utilizing the Scorpion T2 Recoil Pistol Grip with sure-grip texture and extended recoil-taming material to reduce discomfort to the shooter’s hand and thumb, combined with the thin, non-slip Scorpion X2 Recoil Pad. The well-designed stock offers no snag points and features dual-sided QD attachment points. There is also a single-point sling mount insert above the grip that can be faced left or right for shooter comfort.

The ATI Halo Heatshield is a free-floating design with front/rear blocks and silicone pads that provide for no metal-tometal contact with the barrel. The heatshield is constructed of high-strength steel and finished with a matte black powder-coating. A front dovetail rail attachment comes with two 2-inch rails for the convenience of adding accessories and a shield-mounted, front post sight provides for quick target acquisition.

Completing the accessory package is the ATI Halo Side Saddle, which is mounted directly to the tapped receiver on the Mossberg 500. The saddle is constructed of durable anodized aluminum and comes with three Add-A-Shell® units that mount to any of nine possible positions. Each Add-A-Shell unit can be flipped 180 degrees for user-preference of brass up or brass down orientation. A convenient, removable top rail provides for ease of adding optics or mounting systems.
