Sorry, but more times than not......you get what you pay for.
If you want repeatability and ruggedness( take abuse), you are going to have to pay a little bit. I'd say the Armalite mount is the least expensive solution, ARMS rings and a SWAN sleeve being the more expensive.
I have the Armalite mount, and it is excellent and it is worth the money (in my opinion and my experience). It has been returning to zero consistently now for 4 years.
Those Leupold QRW rings do not have a good reputation actually (check out any of the various sniper boards, those rings come up all the time when new people are getting into shooting and see the outrageous costs of some of the mounts available and then see these cheap quick release rings, and since it says Leupold, hell, they must be good,,,right?). Again, you get what you pay for.
And as far as weight goes, I seriously doubt that you would even notice the real weight difference of the entire rifle using the Amalite mount over those Leupold rings.
After many years of buying and then selling off stuff for my weapons, I've learned it is not a good idea to cheap out on the mounts. The expenisve ones are expensive for a reason.
Good luck in whatever you decide.
