The Sireno Carcano is a long scoped bolt-action rifle that can hold several rounds at once. When combined with the fast firing rate and quick reload speed, this makes it ideal for facing several enemies in long-distance combat. This gun has an ammo capacity of six rounds, and can use Regular, High Velocity, Split Point Express and Explosive rifle ammo.
This rifle can be acquired for free during the missions "The Delights of Van Horn" and "Goodbye, Dear Friend"; it will also become available from all gunsmiths after completion of the latter. Additionally, it can be obtained from a house during a rustling activity with Uncle.
In Online, this sniper rifle is available from all gunsmiths after reaching Rank 50.
- The Carcano Rifle is based on the Carcano M91/38 Short Rifle.
- The Carcano M91/38 is anachronistic as the in-game model was not manufactured until 1938. However, the in-game model has the rear sight of the M91 Long Rifle, which would be more period accurate.
- The Carcano M91/38 Short Rifle gained infamy for being the gun that assassinated President John F. Kennedy.
