Another alternative nobody mentioned is the Saturn Boone...
As for epoxy only sticking to the mount and not the receiver--- ?? It'll bond to both sides equally well. Epoxy as a bedding compound? Sure, it's "reversible" and won't permanently harm the gun, but an "Oh my god, what was I thinking" royal pain in the ass to remove if/when it comes time to do that.
One might say to just apply release agent to the surface of the rifle- problem solved. Yes, but then you're not getting the whole benefit of the epoxy which would be to reinforce the mounting screw(s) of a single point mount.
Just buy the Lightfoot mount and ride off into the sunset.
