I sent a Weather Warrior back for the same thing, They told me it was fine ! LOL I was using a Leupold one pc base they said I should use a 2 pc base ? And lap the rings. LOL It was .045 difference in height ! They recomended Weaver bases to me, I shimmed my Leupold 1 pc. I told them a 600.00 dollar rifle with an 800.00 Zeiss scope is not getting 5.00 bases ! I hope you have better luck with their customer service then I did, I had a real winner. Forgot to mention, The guy at Savage told me " Thats the first he's heard of it"
