Ruger 10/22 Yukon Silhouette Stock by Revolution These right handed Thumbhole Yukon stocks for the Ruger 10/22 have a rich looking, classic style that's functional and timeless... That's because the original design focused on fit, function, and accuracy. The whole idea behind these stocks is to convert a Ruger 10/22 into an adult sized rifle that's geared to deliver adult sized accuracy: The thumbhole positioning of your hand gives better trigger control. The height of the cheek rest is specifically set to line your eye up naturally with a riflescope... Which minimizes parallax error and reduces tension in your hold. The EABCO "Silhouette" barrel channel is specifically sized to fit and support non-tapered .920 diameter target barrels. And the forend is shaped to accommodate push/pull bench resting as well as off hand and bipod shooting. Swivel studs are not included. You may purchase the swivel stud kit for a do-it-yourself installation.
