I just polished mine and pressed it in. Make sure you shape the feedneck to clear your bolt first as the arch is not correct. I dremelled my arch slightly and wrapped some sandpaper around an old metal bolt to sand it perfectly.
I used some red loctite to hold it. The loctite was not necessary as it was a pain to remove even when I test fit it without loctite (test fit to make sure the bolt would clear).
