I had covered the front, sides, and bottom of the recoil lug with two layers of tape to give me a little room as suggested in the instructions and by others. The little extra room in front and to the sides is to aid in pulling the barrel off the stock to clean it later on. When I pulled it out this morning, the outer layer of tape stayed stuck in the epoxy. It's in there good and doesn't want to pull out. I'm going to leave it in there instead of messing with my nice clean pocket.
