Don't know what "best" means as there are a bunch that will hold your scope zeroed.
Some of the more expensive mounts/rings will do that in a more compact package. Something like the ARC or Sphur mounts that have the offset clamping screws will really reduce the profile of your scope, not that any of the 34mm scopes are really trim or sleek to begin with. But I have sphur mounts, Nightforce ultralight mounts, seekins, and vortex as well as some cheap off brand stuff in 34mm rings. They all have done the job, but if I was going to buy something now it would be Sphur, ARC, badger or Nightforce knowing that it was rock solid.
