American National Firearms adjustable V-block for the Ruger 10/22. Improve the accuracy of your Ruger 10/22, 10/17, SR-22 or Charger by eliminating the dreaded barrel droop with our adjustable, all stainless steel V-block barrel stabilizer. This one, simple accessory will help turn your rifle into a tack-driver. Our adjustable V-block retainer is especially beneficial on floated or heavy barrels, but will support, stabilize and eliminate droop on all 10/22 style barrels. If you use a carbon fiber or other exotic, lightweight barrel that fits a little loose in your receiver, this is your solution. If you are running out of your scope's elevation adjustment because of barrel droop, this is your solution. If your scope or other optic won't stay zeroed in - you guessed it - this is your solution. This all-stainless steel adjustable V-block includes a non-marring flat-point socket set screw (eliminates surface damage on barrel), precision stainless steel v-block-to-receiver screws, hex wrenches for set screw and receiver-screws and instructions. Rounded corners prevent nicks and ease the installation of tight-fitting stocks. Our V-Block is indestructible and guaranteed forever.
