The Williams™ 71078 FP-Target  Receiver Peep Sight is specifically designed to fit the Ruger .22LR. Williams™ FP-Target Receiver Peep Sights offer shooters unmatched open sight visibility at longer distances than standard fixed open sights. The Williams™ FP-Target Receiver Peep Sight is compatible with a front fiber optic fire sight. Williams™ Fire Sights gather ambient light and reflect it back to your eye, enabling faster target acquisition. Williams™ Sights do not use artificial light sources to create their sight visibility, making them legal to use in states that do not allow artificial light sources on your firearm while hunting. 

This Williams™ FP-Target Sight Set 71078 fits the following firearms:

• Ruger .22LR
