Its short-stroke gas piston operating system does not impart hot carbon fouling back into the action allowing the weapon to run longer with less maintenance and with less wear on internal components than direct-impingement ARs. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls lighter weight and a slimmer profile make the new A4 easier to operate manipulate and employ. For those who demand an AR with unmatched capability and uncompromising reliability and durability the MR A4s remain the top tier solution.
