This Recoil Pad / Stock Extension has already proven itself to be an instant hit with everyone that's shouldered a 10/22 with one installed.  The factory Ruger 10/22 stock is "one size fits all" for kids and adults.  If you're not a kid any more and want your 10/22 stock to fit your adult size, the additional 1" of length that this stock extension adds makes it pretty close to being a perfect adult fit.  Installation is easy with no modifications to  your gun.  Simply remove the two screws that hold the factory steel but plate on and replace it with this one using the same two screws in the same two holes.  Installation is easy and fast!  Throw this one up to your shoulder and you'll never take it off!
