Need more elevation walther kkj

[muzzle flash]

I am shooting a walther KKJ. It has the 11 mm. groved reciever. Scope burris 8-32x 30 mm. tube. I need alot more elevation to reach 300 meter. Is there any known ring or mount combination in which I may obtain needed minutes short of drilling,tapping and installing basses?
THANKS.

Burris Signature Z Rings... you can get offset inserts I believe in 5, 10 and 20 so depending on how much MOA you need they may do the trick.
