KIDD Innovative Design V-Block with Screws For Ruger 10/22 Silver. Slightly longer than the factory v-block to give an increased bedding surface. Also our v-block has more support for the v-block screws for increased stability in your rifle. At times customers ask why we don't offer an adjustment screw. To answer that question we feel it is important that the barrel fit properly without disturbing the harmonics with such an adjustment. This adjustment will likely negatively impact the accuracy of the barrel.
