I know many custom shops will sell precision uppers with a matched bolt. Maybe Noveske does as well?
My question: what kind of accuracy am I sacrificing by buying a stripped upper and dropping in a standard BCG, like a FA from Bravo Company or LMT? Can there really be that much of a difference in headspace? And if there IS, what can I do to minimize it outside of buying a dozen bolts and measuring each one to find the one with the best tolerances?
This is not for duty nor for match shooting, but for shooting on the range and in carbine courses where I prefer to have better accuracy than not. And before someone says it doesn't matter because my ARs can outshoot me, that's not necessarily the case; hence the question.
