FAQS
Can I lap Talley mounts?

We do not recommend lapping any of our mounts. Since they are machined, it really eliminates the need to do so. Since the lightweight mounts are horizontally split, you can lap if you would like. We highly advise against lapping our steel rings. Since they are a vertically split ring, lapping can knock them out of round. Our Picatinny rings, although horizontal split, do not need lapped either. They are a match grade ring and are perfectly round when they come off the machine. Note: If you lap any Talley rings, it will void any return policy since the mounts have been modified


See? No problem.
