Hmm, seems like I had a similar issue some time back. I just clipped the insert over the scope and then placed the upper half of the ring, pushed down and inserted the screws. My biggest gripe with the sig rings is the clamp design. Although I’m sure it’s very adequate, it’s not robust. Seems like a set of Warne rings machined for inserts would be the ticket.

I’m debating refinishing and attempting some checkering on my Boyd’s. What’s the worst that could happen? Lol.
