I've got an SB22 Fixed Kit chassis for a Ruger 10/22 for sale. It's in like new condition, just decided to go another route with a build. It accepts 1913 stocks or braces and has a qd mount on the back as well. It will come with both the picatinny rail forend top cover (seen in the 1st pic) and the smooth top cover as well. This also accepts any AR-15 pistol grip of your choice, but comes with an A2 standard grip. The 2nd and 3rd picture are just for inspiration on what you can do with this on your firearm.
