RE: 10/22 bases and rings
I never use anything but steel rings on ANY rifle. I have millet rings and a weaver base on my 10/22. I would also recommend some blue Loc Tite for the screws on the base. The worst thing in the world is to get the darn thing sighted in and then have it go out of wack because some screws came loose. Blue Loc Tite is not perminent so don't worry but it will hold those scews really well.
Good luck
