The Bullpup Shotgun is a shotgun in Grand Theft Auto V. The weapon is a bonus available to those who purchase either the special or collectors edition and will be available for free in game at Ammu-Nation.
The weapon is based on the Kel-Tec KSG. It has a 14 round ammunition capacity thanks to its dual-tube internal magazine, a moderate rate of fire, about the same as the Pump-Action Shotgun, and like most shotguns, lethal stopping power at close range. While it doesn't do as much damage as the fully automatic Assault Shotgun, it's still a fairly balanced weapon. It is available for free in the Special/Collector's edition of the game after completing the mission, Franklin and Lamar.
Being a rather well-rounded firearm and available after completing the second mission of the main game, it can be used to the player's advantage during missions such as Repossession or The Long Stretch.
