Notes: MOSSBERG 500 (50120) 12 GAUGE 4+1 CAP 3" 5+1 CAP 2.75" Mechanical & Action Features * Pump-Action Operation: Built with a smooth, manual slide action utilizing twin action bars that prevent twisting or binding during rapid manipulation. * Dual Extractors: Equipped with two opposing extractors on the bolt face to engage the shell rim, ensuring highly positive extraction and ejection cycle reliability. * Positive Steel-to-Steel Locking: The bolt features a heavy steel locking lug that locks directly into a matching recess inside the barrel extension rather than against the aluminum receiver, enhancing action strength and safety. Barrel & Receiver Specifications * 28-Inch Field Barrel: Features a long, smooth-bore barrel topped with a ventilated rib to dissipate heat shimmer and improve your sighting plane alignment. * 3-Inch Chamber: Cut to chamber both standard 2.75-inch and heavy-duty 3-inch magnum shotgun shells interchangeably. * Accu-Set Choke System: Machined with internal muzzle threading that accepts the Mossberg Accu-Set interchangeable choke tubes (typically including Full, Modified, and Improved Cylinder) to control your shot spread patterns. * Anodized Aluminum Receiver: Manufactured with a lightweight, high-strength aluminum alloy receiver, reducing overall firearm carry weight while resisting environmental corrosion. Ergonomics & Furniture Aesthetics * Ambidextrous Tang Safety: Features a safety slider switch mounted directly on top of the rear receiver tang, making it highly visible and easily accessible for both left- and right-handed shooters without shifting your grip. * Anti-Jam Shell Elevator: Designed with a lifting gate mechanism that keeps the loading port clear and open while cycling, reducing the risk of skin pinches or feeding jams. * Hardwood Stock Assembly: Furnished with a traditional, checkered wood stock and forend set, complete with an integrated rubber recoil pad at the buttplate to mitigate heavy 12-gauge kickback.
