Mossberg
The Mossberg 940 Pro is a semi-automatic 12-gauge shotgun built for shooters who demand reliability in tactical and home-defense roles. With an 18.5" barrel and 7+1 capacity, this gun handles fast, accurate follow-ups without compromise. The receiver is drilled and tapped from the factory—no gunsmithing required—so you can mount optics immediately using the included adapter plates for RMSc, RMR, Docter, or Leupold footprint accessories. This is a shotgun that comes ready to work.
Mossberg's gas-vent system runs cleaner than traditional piston designs, keeping you in the fight longer without excessive maintenance. The forend incorporates an integral heatshield, protecting your support hand from barrel heat during sustained fire. You get quality ghost ring sights with a front fiber-optic element and low-profile protective wings, so you're covered whether you're running optics, irons, or both. The durable Cerakote finish in tungsten gray protects the barrel and aluminum receiver from corrosion and wear—practical coating, not flash.
The 940 Pro handles shooters of different frames thanks to an adjustable length of pull that ranges from 12.5" to 14.25". That means you, your tall friend, and whoever borrows the gun later can all get a proper fit. The synthetic stock won't swell from moisture or humidity, and the ergonomic bolt release is positioned where your thumb naturally falls. The barrel includes M-LOK mounting slots for tactical accessories, and the whole package delivers genuine tactical features without theatrical styling.
