I really love the Weaver Pro-View mount/ring. Cheap, lightweight, and they have a really nice and clean look to the installation...

The only thing is, they're useless with a 40mm objective and the stock barrel unless you remove the rear sight. Also, if you have a >40mm objective, they don't work. Very low objective to barrel clearance, which is a good thing.

Gunaccessories has them listed for $15.95. They're a one piece ring/mount system. I like them because I don't ever plan on removing the scope, so a weaver rail is just extra bulk to me. Here's another picture of what they look like:

They fit the factory tapped holes.

Oh, they've VERY solid too. Every installation I've done with them, the scope (provided it's factory centered) needs very little adjustment.

Yeah, they're 1" rings. With a 40mm objective you'd either need to remove the factory rear sight off the factory barrel, or get a bull barrel and you'll be fine.
