I'd be more suspect of indexing. How precisely is the front sight base/gas block indexed to the barrel extension pin that indexes the barrel extension to the upper?
I think this is a good place to start and since the barrel will be off I can lap the receiver ( cus I can ) . I'd like to look at all that this weekend but I recently moved my reloading "room" to a reloading "area" which is much more confined . I've not even set up my vice yet and not sure there is a workable space for it . There's room for the vice but not the extra space needed to hang the upper out from . I'll need to look at all that tonight and see if it will work .

I'll take pics as I go FWTW lol .
If Jesus had a gun , he'd probably still be alive !

I almost always write my posts regardless of content in a jovial manor and intent . If that's not how you took it , please try again .
