LIke Robin said, release agent. Bedding the rail is no different from bedding the Action, or anything else for that matter. You apply release agent to the Action surfaces & the compound is applied & sticks to the rail. Many, many people do this. Of course someone is going to chime in to call or send it to Fred (Sharpshooter), to check if the Action is warped because he fixes that. So I’ll save them the time. That’s always an option. Personally, I’d verify correct screws as Robin pointed out & bed the rail. Easy, cheap & works. If you were near me, I’d bed it for you for free.

Here’s a decent video from from my boy Vaughn. There’s are dozens of videos showing how to, so don’t hesitate to watch many. Also, I prefer using the Devcon “Plastic Steel” epoxy for all my bedding needs, but that is a personal thing based on my own research & experience.
