Hello,
On my ongoing AR15 build the complete upper I purchased came with a stock BCG. I purchased one of the custom M16 BCGs from Spikes Tactical and it seems to function just fine -but- I'm reading I need to pull the extractor and check the rifle with a set of go / no go headspace gauges now.
Is this true? Is it something that has to be done every time you replace part of or the entire BCG?
