Moving on to another question about the roller-delayed blowback action of the Cetme .308 and several H&K firearms (and this is a fundamental question): Assuming that bolt gap determines (or indicates) the length of delay between firing and the unlocking of the bolt assembly (timing), does excessive bolt gap INCREASE the delay so that the rifle might not cycle, or does it REDUCE the delay so that the bolt assembly rebounds too soon and too forcefully, thus causing case head separations and excessive wear on the rifle? Even on this basic question, there is conflict between people who seem to be well-informed. This conflict seems to imply how difficult it is to understand this system. But note that in the thread cited below, citations and authorities are asked for and given.
