[QUOTE="Veteran, post: 2439576, member: 118038"] No one has said that muzzle press is greater than chamber in fact one poster put up a nice graph of the profile of chamber pressure peaking and the decline along the barrel out to the muzzle. The only thing Im saying is when you add a can, that muzzle pressure you saw without a can wont be as low as it was before. Call it restriction, call it a volume holding tank, call it whatever, but the gas does not escape as quickly as it did before the can. So in a gas gun we see this as gas has no where to go but into the gas port, down the gas tube, and into the chamber slamming the bolt back. Semi autos get over gassed when a can is added and the gas block which acts as a regulator valve has to be used to restrict or turn down too much gas from going to the chamber. [/QUOTE]
