Mossberg 500

December 20, 2009

 

The Mossberg 500 is a shotgun manufactured by O.F. Mossberg & Sons. Rather than a single model, the 500 is really a series of widely varying hammerless, pump action repeaters, all of which share the same basic receiver and action, but differ in bore size, bar Contents, Barrel length, choke options, magazine capacity, and “furniture” (stock and forearm) materials. Other model numbers included in the 500 series are the 590, 505, and 535.

Basic features

Introduced in 1961, all model 500s are based on the same basic design. Originally using a single action bar this was changed to dual action bars in 1970, which are (at least in theory) less likely to bind than a single action bar design. A single large locking lug is used to secure the breech. 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 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. (more…)
