PRi's M84 Gas Buster® Charging Handle for the 9mm AR platform.  This safety device with ergonomic design that helps divert gases and dirt away from the shooter. This handle comes with the Combat style latch.    The charging handle is constructed of T6 7075 hard coat black anodized aluminum with a steel latch.  The 9mm is different than the Standard gas buster in how it engages with the BCG.  There is no ramp at the end that P{RI uses for extra strength.
