I like the Redfield Jr One piece scope mount. Stable, completely windage adjustable too. You can also grind the opening width and adjust them to fit your receiver opening exactly. I think they look better that way. You do not have to grind off the stripper clip guide off the receiver either with these, they have a built in hump to lear the guide.
In the photo you can see that I've adjusted the front opening of the mount to exactly co-oincide with the receiver opening. That is a YUGO action By the way (in 257 Roberts). I'm trying to remember now, but I think I use the 93-96 Redfield Jr Mount on Yugo's (they are the same length as a 96) and the K98 Redfield on full length receivers.
The best part about these mounts, you can actually use them as a drill guide to mark your scope mount holes. I set the front holes based on the Top Dead Center of the receiver ring (sometimes it's marked on the receiver) and mark and drill the front holes using the base. Once those are in tapped, I mount the base temporarily to mark and drill the rear screw hole.
The big windage screw will forgive a lot of error in a less than perfect placement of that screw hole.
