Mossberg 940 Pro Field Semi-Auto Shotgun
The Mossberg 940 Pro Field represents a modern approach to the working shotgun. Built on a proven gas-operated platform, this 12-gauge delivers reliability and ease of maintenance—the gas system runs up to 1500 rounds between cleanings, a testament to its robust design.
Durability and Corrosion Resistance
Mossberg has invested in corrosion-resistant internals throughout:
- Nickel boron-coated gas piston and rings
- Nickel boron-coated magazine tube
- Nickel boron-coated hammer and sear
- Nickel boron-coated shell stop
- Anodized follower for smooth, reliable feeding
These refinements ensure the 940 Pro Field will perform in demanding conditions.
Ergonomics and Handling
The shotgun features an enlarged and beveled loading port for quick reloads, while an elongated elevator ensures smooth shell cycling. The adjustable synthetic stock offers 1.25 inches of length-of-pull adjustment (13" to 14.25"), accommodating different shooters and clothing layers. Both stock and forend incorporate Mossberg's signature texturing for a secure grip in wet or gloved conditions.
Sighting and Accuracy
A front fiber optic sight aids target acquisition in varied lighting. The 28-inch vent rib barrel is drilled and tapped for optics mounting, and includes Accu-Set choke tubes for pattern customization.
