The Ruger .22 caliber model 10/22 Combo is a front and rear sight set that includes a unique rear Litepipe folding sight that allows the shooter to use a detachable scope mount without removing the fiber optic sights.

The Ruger 10/22 Combo is designed to replace the factory sight on standard Ruger 10/22 long rifle barrels.
