What kind of rig are you mounting on? Is this a standard R700 type action with 20 MOA picatinny rail? What is the profile of your barrel? I was using .94" high rings with a custom media palma contour barrel and it worked great with just enough room for the Tenebraex caps to clear without touching the barrel; however, when I put the Minox on my rifle with a PROOF Sendero contour the caps slightly touched, going to 1.00" high rings allowed it to clear just fine.
The below image shows the Minox in the .94" high rings with the medium palma contour bbl
