Not my only dnz mount - DNZ Products Rifle Scope Mounts for Ruger

I have these mounts on a couple of centerfires, 1st time on a rimfire.
These have to be the most rugged scope mounts on the market.
Even though scope position is slightly limited with the fixed position rings, I have always been able to find that "sweet spot" for eye relief, The medium height was perfect for a 40mm objective on a 10/22
