I would say yes and I've used some for 50 years. My favorite mounting system is the talleys but they are a lot more expensive.
The other poster said to use the rings with screws on both sides instead of the screws on one side, and I would concur with that.
But if you already have the other, lock it down and go hunting!
Asking if Weaver rings and bases are "good" I'd say is akin to asking if the 30/30 is a decent deer cartridge. Plenty of people might suggest another cartridge/caliber, but very few (any???) would say that the 30/30 is anything but a great deer killer AND that a weaver base and ring set will do anything but securely hold your scope in place. Some might be purtier and many are more expensive, but not sure if any do their job any better.
The only issue I have with the Weaver rings with the screws on one side, is the scope will tend to clock around when tightening the screws. Just takes a little extra effort to keep the crosshairs straight. After eveything is in place it tends to stay there. They aren't a work of art but very functional.
