Mossberg 940 Pro Tac 12 Gauge 18.5" 7-Round Optics Ready Shotgun

The Mossberg 940 Pro Tactical 12 Gauge shotgun with 18.5" barrel is purpose-built for law enforcement, military, and professional security applications where reliability and tactical flexibility demand an semi-automatic platform. Weighing 10.69 lbs, this inertia-driven semi-auto delivers the speed and capacity of a modern fighting shotgun while maintaining the legendary durability Mossberg brings to patrol and breach operations. The 7-round magazine capacity provides sufficient reserve ammunition for dynamic tactical scenarios, while the optics-ready receiver eliminates the need for aftermarket mounting adapters.

The 940 Pro Tactical employs Mossberg's proven inertia-operated action, which cycles reliably across a wide spectrum of 12-gauge ammunition—from reduced-recoil institutional loads to full-power buckshot—without manual cycling adjustments. The 18.5" cylinder-bore barrel provides tighter patterns suitable for close-quarters engagement while maintaining velocity for intermediate distance work, and the integrated optics-ready surface on the receiver accepts standard Picatinny rail adapters for red-dot sights, carbine optics, and night-vision systems. Hardened steel internals and a corrosion-resistant finish ensure this shotgun performs in demanding environments where regular maintenance is limited.

This model is ideal for tactical teams, riot-control operations, breaching, and home-defense applications where semi-automatic rate-of-fire and ergonomic control outweigh pump-action simplicity. The lightweight profile reduces shooter fatigue during extended deployments, and compatibility with standard 12-gauge ammunition ensures no supply-chain dependency. The optics-ready platform allows operators to pair this shotgun with mission-specific sight systems—from CQB red dots to longer-range sluggun configurations—making it equally effective in building clearance or perimeter defense roles.
