Ok, so I bought a Aimpoint Pro and wanted to mount it on my 10/22. The scope rail which came with the 10/22 had grooves which were too narrow to fit the crossbar on the Aimpoint. I went to the local shop to buy a rail with larger grooves and they gave me a Weaver brand 10/22 rail when I explained my problem. It doesn't fit either. I assume I need a rail with a Picatinny groove pattern. How can I tell and what do you recommend?
