The Mossberg 500 is an American-made pump-action shotgun chambered for 12 gauge, 20 gauge and .410 bore cartridges. The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials.


Introduced in 1961, all Mossberg 500s are based on the same design, although there are a multitude of different models available, with varying barrel length, magazine capacity, sights, bore size, choke options, finishes and "furniture" (stocks, grips etc.). Perhaps the most notable variant of the 500 is the Bullpup model, which houses the shotgun in a distinctive bullpup stock. A unique item offered by Mossberg for the Model 500 is a line launcher kit, which uses a special blank cartridge to propel a shaft with an optional floating head and a light rope attached to it; a canister hung below the barrel holds the line spool.

The Mossberg 500 is notably used by the United States military.

Notable Users

Billy had a Mossberg 500 with the stock removed underslung on his M16 assault rifle during the mission to Guatemala.


Mossberg 500 Bullpup, several of which were seen in Predator 2.

Several LAPD officers were equipped with Mossberg 500 Bullpup shotguns during the gang warfare of 1997. Garber also carried one when confronting Mike Harrigan after the Los Angeles hunting party left the city.

Behind the Scenes

In Aliens vs. Predator, the ZX-76 Shotgun seems to incorporate some elements from a pistol-gripped Mossberg 500, specifically the pistol grip itself and the forward grip.


  • While Billy is never shown prominently firing his shotgun in Predator, there is a brief instance where he appears to run out of ammo for his rifle, and fires off a single shot before the film cuts to the next scene; it is often overlooked as he is in the distant background in this scene and there is no sound effect for his shotgun firing.
