I used some PC-7 epoxy (I think it’s an automotive epoxy similar to JB Weld) to bed a DNZ Grim Reaper one piece mount to my rifle. I also slipped a piece of .015”brass shim at the rear edge so I could get the maximum out of the Leupold CDS.

Other than scrape the heck out of the bottom with a knife, is there a chemical that would soften it easier for removal? I was hoping acetone might help? Thanks.

A heat gun should soften the epoxy a bit.

Believe it or not, repeated soaks with white vinegar.

Heat will break the entire connection, not just the excess. And it has to be 200 degrees. To get the excess, i have sliced down into it with a blade and then use a screwdriver or something like that to pry against it and it will pop off.
