That's not entirely true. A sloppy fitting set of receivers will not provide as much accuracy as a tight fitting pair. Will it matter enough to notice? Depends on how well you shoot and the type of shooting.
The barrel and trigger will make much more of an impact to overall accuracy, as well as how the parts are machined and fitted.
EXACTLY. If you could get down in a nice comfortable shooting position with a bolt action rifle...and someone could walk over and wiggle the action inside the stock...would you expect any reliable accuracy? Not likely.
So if your AR upper/lower fit has any wiggle...why would that be any different?
It's not so much the lower...its the fit between the pair.
