940 JM PRO OPTIC-READY, BLACK MULTI CAM
Item # MB 85166 MSRP $1,260.00PRODUCT DETAILS
TECH SPECS:
The Mossberg 940 JM Pro Optic-Ready 12 Gauge Semi-Auto Shotgun (Model 85166) is a competition-bred, high-performance shotgun designed with input from world-champion shooter Jerry Miculek. Built on Mossberg’s rugged 940 platform, this model features a 24″ vent-rib barrel and an optic-ready receiver with patent-pending Shield RMSc micro-dot sight cuts for improved eye alignment and faster target acquisition straight from the factory.
Inside, a clean-running gas-vent system and specially coated internal parts deliver smooth cycling and reduced maintenance intervals, while the competition-level loading port, elevator, and follower enable fast quad-loading for competitive use. Externally, the adjustable synthetic stock (length of pull, cast, and drop) and streamlined forend with Mossberg’s signature texturing provide comfort and control under pressure.
Additional features include a quick-empty magazine release, drilled and tapped receiver for accessories, and a HiViz fiber-optic front sight for rapid target acquisition. With a 9+1 capacity, versatile performance, and competition-ready design, the 940 JM Pro Optic-Ready is built to excel in 3-gun, tactical, and defensive environments.

Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
