I mounted Warne QD rings on my Ruger Hawkeye African .375 Ruger, before my last trip to Africa. These rings mount on the fixed Ruger factory base.
What I found was that accuracy suffered with these rings- I simply could not get the sub-MOA accuracy I had been getting with the Ruger rings I was using before. Thought it might be the scope, but tried another scope with the same results.
I went back to using the Ruger rings, and the accuracy returned! If I ever need to use the irons, a quarter in my pocket removes the scope in seconds, and it's good to go.
Re-mounting the scope might need a shot or two to confirm zero, but that can be done back at camp, or wherever.
I now have two sets of Warne QD rings for sale, that fit the Ruger base.
