What is an Automatic Shotgun?

An automatic shotgun is a type of firearm that uses gas or recoil energy to cycle the action automatically, chambering a new round and ejecting the spent shell with each trigger pull. This enables the shooter to fire multiple rounds rapidly, making them highly effective in close-quarters combat and self-defense scenarios.

Advantages of Automatic Shotguns:

Automatic shotguns offer several advantages over other types of firearms:

  1. Firepower: With the ability to fire rapidly, automatic shotguns can deliver a significant amount of firepower in a short amount of time, increasing the chances of hitting the target.
  2. Versatility: These shotguns can accommodate various ammunition types, including buckshot, slugs, and specialty rounds, making them suitable for different applications.
  3. Intimidation Factor: The sound and sight of rapid-fire shotguns can be highly intimidating to potential threats, potentially deterring them from continuing their actions.
