I did 2 of my others but only slightly lapped so most of the hca was still intact.Whatever it takes. I’ve done every one of my other receivers and it’s been very minimal. Haven’t really had one that that was very far off. I wouldn’t worry about exposing some of the raw aluminum. It’s going to be covered by the barrel and torqued to at least 40 pounds,nothings going to hurt it.
