The Gas Buster® charging handle with Combat latch is a safety device with ergonomic design that diverts harmful gases, oil and dirt particles away from the shooter. This is a PRi Patented product. Safety approved & used by the US Marine corps. This product doesn’t work as well with left hand shooters because of the gas porting properties but works better than a standard charging Handle. Handle is constructed of T6 7075 hard coat anodized aluminum and is available with 2 colors; black and FDE.
