I did on a couple of rifles but would not now. I will epoxy bed bases and rails if they appear to need it but most don't. The reason I wouldn't epoxy now is if I were on a hunt and dinged a scope it would be a pain to swap out with out the proper tools. Loctite or even nail polish has not let me down yet even on the medium bores.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
