Lapping for accuracy

[lazyengineer]

I'm not really worried about the other's. My testing is enough to proof to me that lapping is for a square bolt lock up and bolt life and bedding if for accuracy.

I think most people who say that lapping the reciver made the gun shot better, had some other issue and didn't know it and fixed it without knowing it and then turn around and account it to lapping the reciver.

That's what I think.
