Rifle Scopes Sphur Mount Ring Inserts

[mountainman308]

I’m looking at Sphur mounts for my NF NX8. I’d like a 30 MOA taper, but it seems that the Sphur 30 mm mounts only go up to 20 MOA. Does Sphur make any inserts to put a 30 mm scope in the 34 mm mounts with the 30 MOA taper? I couldn’t seem to find any.
