Navy SEALs use the Benelli M4 Super 90, Mossberg 590, and Remington 870 combat shotguns. The Benelli M4 Super 90, also known as the M1014 Joint Service Shotgun, is generally preferred. It was first delivered to the U.S. Marine Corps in 1999 after intense testing. The M4 Super 90 is a gas-operated, semi-automatic, magazine-fed 12-gauge shotgun with an extended buttstock. It features an entirely new “auto-regulating gas operated” (ARGO) system that eliminates the need for complex mechanisms. The M4 Super 90 self-regulates for cartridges of varying lengths and power levels, firing 2.75 in. (70mm) and 3 in. (76mm) shells of differing power levels without any operator adjustments, and in any combination. This shotgun also has a Rail Integration System designed to attach scopes, laser illuminators, night vision sights, and flashlights.
The M4 Super 90 is built on a modular assembly basis, enabling it to be modified without any tools. This is especially useful in the field, in a changing tactical environment. This weapon is reliable and durable, and can operate for at least 2,500 rounds without having to replace any major parts. The M4 Super 90 (M1014) is planned for issue to all the U.S. military services. It replaces the Remington 870, Mossberg 590, and Winchester 1100/1200 tactical shotguns. The M4 Super 90 is durable, and reliable in all weather conditions.
