The Mossberg ATPS 500 is a pump-action shotgun designed and manufactured by O.F. Mossberg & Sons since 1960. Other shotguns in the same series as the Mossberg 500 include the 590, the 505 and the 535.
The Mossberg 500 has a conventional design without any advanced design features. It is available in civilian, military and security variants. All of these versions have the same basic design, except for a few changes.
The shotgun is designed to fire the 12 gauge round. However, versions for the 20 gauge round and the .410 bore ammunition have also been designed. The shotgun feeds from a six-round tubular magazine and has very good firepow
The Mossberg 500 was designed primarily as a military weapon. This becomes evident from the inbuilt bayonet mounting and rails for mounting optical scopes. The shotgun can also fire solid ammunition. However, since the barrel has no rifling, it may not be accurate for long distances.
The Mossberg 500 has a long history of service with the United States armed forces. It continues to be in service with various branches of the US military. In 1999, the US Army officially adopted the M1014 Combat Shotgun. However, it continues to use the Mossberg 500 and new orders continue to be placed.
Variants of the Mossberg ATPS 500:
>> Field Models: These are designed for sporting and hunting. These come in a variety of barrel lengths and furniture. Some versions also have rifled barrels.
>> Special purpose Models: These are for self-defence, police use and for use by the military. These have shorter barrels and some versions come with pistol grips for better handling.
>> Law enforcement Models: These have heavier barrels, metal safeties and trigger guards. These are designed to pass stringent requirements of the US Army and are more robust.
