Reading the instruction manual that came with my new M18 last evening, it says to epoxy bases. "... ensure that the mounting base is not just screwed on, rather has additional and evenly applied high-quality two-component adhesive used to stick it in place."

What say my expert Campfire advisors? Should I epoxy scope bases? If so, how do I get them off if I ever want to?

I have used LocTite in blue or red a few times to ensure even contact between bases and receiver but usually not. I have Talley one-piece base/rings ready to put on the rifle. If I use epoxy it would probably be marine grade since I have some on hand and we hunt the wet.

FWIW, the manual also says to never shoot hand loads, and its use of English is faintly odd, calling the bolt the chamber most of the time.
