Sukhoi_fan Posted June 3, 2020 Share Posted June 3, 2020 A buddy of mine who owned a gun store for several years was telling me today that he understood that a Benelli M4 will still cycle with both pistons broken, that it was designed to still operate on blowback force when the gas system isn't working. Any truth to that? Has anyone ever tried shooting a Benelli M4 with both pistons out? Quote Link to comment Share on other sites More sharing options...
