I'm a little confused and hope someone can help. For a lower 1/3 co-witness do you use the shim provided or not? The manual says for lower 1/3, simply install as provided, and mount will be 40mm from base. For absolute co-witness, remove the shim..will be 37mm high from base.As provided the shim is not installed but the documentation seems to be wrote as if it was..?
I've got it with no shim and it looks pretty dead absolute, the manual just got me wondering....
Use the shim and go higher for lower 1/3, correct?
