So I have a couple uppers (Vltor - forged; Gibbz - billet) that I want square the face up on.
The Gibbz is really nice and tight and seems to be just about there already when I put the barrel on. I think any lapping on this will be minimal.
The Vltor is a different story. It has more slop in the ID than the Gibbz and the face is definitely not square. The Gibbz will be a target gun and the Vltor will probably be a 14.5 Grendel or so.
So I got the lapping tool last night from Wheeler and red flags went up when I saw it was made in China.
I set the tool down into the Gibbz and held it up against the light and rotated the tool to see if there were gaps. There was the slightest of gaps on one side and as I rotated the through to 180deg the gap would close.
Now if the face of the tool was square with the shaft and consistently square around the entire diameter of the face, the gap should stay the same as you turn the tool in the receiver.
Has anybody had issues with the tools not being square?
If so, did you square it up yourself or let a shop square it up for you?
I don't think I want to roll the dice and send it back and possibly get another defective one.
