As for a mounting system for your scope, The Leupold QR bases, and rings are a good choice. I use this system on both muzzleloaders, and centerfire rifles. I like the idea of being able to take the scope off when I clean. When I reattach the scope it is right on target. One note, Leupold also has QRW rings which attatch to a Weaver style base, do not confuse these with the regular QRW rings.
