Product Overview
Mossberg MB85144 is the 940 JM PRO tactical semi‑automatic shotgun sold as a package quantity of 2 (SKU MB85144).

Why This Product
These verified attributes matter for procurement and stocking: the Shield RMSc optic footprint on the receiver defines which red dot mounts or optics can be fitted without custom machining (product-276171:f009). The oversized charging handle is an identified ergonomic feature that informs user handling and manual cycling considerations (product-276171:f010). The enlarged/beveled loading port is a documented loading and feeding feature relevant to faster shell insertion or eased reloading at the loading port (product-276171:f011).
