Ruger 10/22, Nikon P-Rimfire, Burris Zee Rings, Video 3: Picatinny/Weaver Base Rail

Brownell's website will not allow for a link. For the Ruger 10/22 research "Ruger 10/22 Nokak Rear Sight."
Due to the tight tolerances of a quality Picatinny rail by a reputable company, you may not have to lap the Burris Zee Rings for your alignment to be perfectly aligned for your scope. You will need to verify that the alignment is correct but more than likely you will find the alignment will be pretty close to perfect. God bless and thanks for watching. Highboy
