Dear Mr. Jared,
thank you for contacting us.
You can choose these one:
Which suits Blaser r8 great.
And you can also choose the BASIS VARIO:
On the BASIS VARIO you can mount a scope which is zeroed on a different rifle on these mount and zero it with these mount (screwes on the bottom of the mount). Then you can put the scope back on the previous rifle and it will be zeroed.
Should you require any further assistance, please do not hesitate to contact us again.
