This enables the shooter to simply pull back the bolt slightly to the rear and the bolt automatically releases, thus eliminating the need to push up and backward on the bolt lock mechanism to release the bolt. This 10/22 accessory is practically a must-have and is a customer favorite. Easy drop-in installation. Does not fit the Ruger 10/22 Magnum. But here you can find one for the Ruger 10/22 Magnum
