Scope (3x)

Handgun scopes differ from rifle scopes in that they must make use of a handgun's smaller size for mounting, and are typically used at arm's length instead of near one's eye.

Battlefield 3
Although not a selectable attachment, a 3.4x scope is available for the .44 Magnum by unlocking the .44 SCOPED variant.

Battlefield 4
The Scope (3x) is available on some sidearms, such as the .44 Magnum.
