Double-Barrel Shotgun

A Double-Barreled Shotgun is a break-open action shotgun that has two barrels lined up in parallel to each other allowing for two shots to be fired in quick succession. Some shotguns can be sawed-off, removing the buttstock and most of the barrel length, giving them very high mobility at the cost of range and accuracy.

Battlefield Play4Free
The Scattergun is a weapon featured in Battlefield Play4Free for all kits. Despite being a shotgun, it is used a sidearm. It is useful for those lacking close-range capabilities, like the Recon class, without having to change the primary weapon.

Battlefield Hardline
The Double-Barrel Shotgun is a weapon featured in Battlefield Hardline.

It is an unlock available after completing the Enforcer Syndicate assignment and is available for the Enforcer class. It cannot mount or unlock most attachments due to the absence of rails on the weapon, only coming equipped with its default Iron Sights. A Stock can be equipped, which helps to reduce recoil at the cost of some mobility. The Heavy Barrel increases the barrel length, improving range and accuracy, while reducing mobility.

It boasts an incredibly high damage model and can fire quickly, but has a small ammo capacity of two shells and extremely high recoil as a trade-off.

Trivia
In Battlefield Hardline, the in-game stats incorrectly describes the rate of fire as "pump action".
