"A 40mm shotgun round consisting of 12 tungsten darts. Its effects are devastating at short range. Although it is considered a multi purpose round , it is most effective in close quarters during urban operations."
— In-game description
The 40mm Shotgun is a weapon attachment found in Battlefield: Bad Company 2. It is simply a canister round that is fired from a 40mm grenade launcher. It is unlocked after getting 11000 points with the Assault class. It is loaded and fired exactly like a grenade, except that no compensation must be made for a ballistic trajectory. It inflicts very high damage against infantry, has a slow reload time, and a relatively short effective range. Achieving kills at medium range is possible, but improbable. The 40mm Shotgun deals the most damage of all shotguns and has no damage drop off.
When the player switches to their shotgun in Bad Company 2, they flip up the leaf sight on their rifle even though they serve no purpose with the 40mm shotgun.
The red-orange color of the shell used by the shotgun differs from that of the standard gray shell of the 40mm grenade launcher in Bad Company 2.
The shotgun in Bad Company 2 actually benefits from Magnum Ammunition, which does not apply to the other underbarrel launchers, as well as Grenade Vest.
The 40mm shotgun makes any type of sight on theAEK-971disappear when equipped in Bad Company 2.
