Mossberg 500 Development

Introduced in 1960, all model 500s are based on the same basic concept designed by Carl Benson. Originally using a single action bar that was known to bind and even break, this was changed to dual action bars in 1970, following the expiration of Remington’s patent on the double action bar design. A single large locking lug is used to secure the breach.

The magazine tube is located below the barrel and is screwed into the receiver. The slide release is located to the left rear of the trigger guard, and the safety is located on the upper rear of the receiver (often called a “tang safety”).

Sights vary from model to model, from a simple bead sight to a receiver-mounted ghost ring or an integrated base for a telescopic sight. Most models come with the receiver drilled and tapped for the installation of a rear sight or a scope base. The factory scope base is attached to the barrel via a cantilever-type mount, which places the scope over the receiver but keeps it with the barrel if the barrel is removed.

Intended for use in harsh and dirty conditions, such as waterfowl hunting or combat, the Model 500 series is designed to be easy to clean and maintain. All Model 500s feature interchangeable barrels (given a particular gun’s magazine capacity—a barrel designed for a five-shot tube will not fit a gun with a seven-shot tube), which may be removed without the use of tools, by loosening a screw on the end of the magazine tube, allowing the barrel to be removed.

Dual-action bars connect the fore-end to the bolt, and generous clearances between the steel action bars and their receiver channels reduce wear on the aluminum receiver while allowing the shotgun to function with the presence of dirt or debris. The Model 500’s bolt locks into a recess located on the top of the steel barrel instead of the receiver itself, thus allowing the use of lightweight aluminum instead of steel. The trigger housing and safety button are made of plastic to reduce the cost.  You can also upgrade trigger housing and safety button with aftermarket parts that perform much better.
