I'm building a custom Win M70 and am considering having the bolt jeweled again. Is there any coating that can be applied that would reduce friction and allow the jeweling to wear less? Would DBC do the job?

Thanks, Dinny

I have used it, but not on a jeweled bolt. It does what they say it will.

Thanks Craig!
