Mossberg 940 SPX Shotgun 12ga 3" Chamber 7rd Magazine 18.5'' Barrel Black Ghost Ring Sight$946.18
Availability: In Stock
The Mossberg 940 SPX is a semi-automatic tactical shotgun built for serious shooters who demand modern features without compromise. This 12-gauge autoloader runs on Mossberg's proven gas-vent system and feeds reliably from its 7+1 capacity magazine tube, making it equally at home on the duty line, in competition, or for home defense. The 18.5" barrel with Cerakoted Flat Dark Earth finish delivers a compact platform that doesn't sacrifice performance, while the 3" chamber handles standard and magnum shells seamlessly.
What sets the 940 SPX apart is its forward-thinking optics integration. The receiver ships optic-ready with a Shield RMSc footprint already mounted, plus three additional adapter plates that let you run RMR, Docter, or Leupold footprint optics—giving you real flexibility to dial in your preferred red dot. Built-in fiber optic ghost ring sights serve as a fast, reliable backup. The forend brings the heat with an integrated shield, multiple M-Lok slots for lights and accessories, and quick-detach ports so you're not locked into one configuration. Up front, a Vang Comp 6-shotshell carrier keeps extra rounds immediately accessible.
The ergonomics matter too. An oversized safety and bolt release make operation fast and sure, even with gloved hands. The adjustable length-of-pull stock (12.5" to 14.25") fits different body types and shooting styles, and QD ports on the stock let you swing on a sling in seconds. The drilled and tapped receiver opens the door to even more customization down the line. Mossberg equipped it with a cylinder bore choke from the factory, giving you a wide spread pattern right out of the box.
The 940 SPX strikes a smart balance: modern tactical features, proven Mossberg reliability, and the weight (7.25 lbs) and length (37") that make it genuinely manageable in tight quarters. It's not trying to be everything to everyone—it's designed for the shooter who knows what they want in a modern semi-auto shotgun.
