Mossberg 500 Serial Number History series#

The forend can then be moved to the rear, allowing the bolt and bolt carrier to drop out, and then the forend can be removed by moving it forward. The elevator can be removed by putting the gun on safety and squeezing the sides together, freeing the pivot pins from the receiver. The trigger assembly, which includes the trigger, hammer, sear, and trigger body with guard, can be removed by pushing out one retaining pin and pulling downwards on the guard (if a pistol grip is installed, it usually must be removed first as virtually all such grips obstruct the removal of the trigger body). The bolt locks into a locking lug located on the top of the barrel, ensuring a solid bolt-to-barrel connection and not relying on the receiver for any locking strength. 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.

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. 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. Most models come with the receiver drilled and tapped for the installation of a rear sight or a scope base. Sights vary from model to model, from simple bead sight to a receiver mounted ghost ring or an integrated base for a telescopic sight. 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'). The magazine tube is located below the barrel, and is screwed into the receiver. A single large locking lug is used to secure the breech. 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. Introduced in 1961, all model 500s are based on the same basic concept designed by Carl Benson.

Model numbers included in the 500 series are the 500, 505, 510, 535, and 590.
