    GIBBZ Arms upper
    ---------------------
    – GIBBZ Arms Patent Pending Left Side Charging Handle
    – Non-reciprocating with detent to keep the charging handle forward during operation
    – Uses all Mil-Spec and most Custom Bolt Carriers without modification
    – Beveled Ejection Port
    – Full 15 Slot Picatinny Rail
    – Rear Bolt carrier door to allow for easy bolt carrier removal and still keeping gasses in during operation (important for suppressed fire)
    – Compatible with Mil-Spec and most other lower receivers.
    – Included is our Enhanced Cam Pin which is optimized for our side charging upper with Melonite coating.
    – Charging handle cover for keeping operating gasses in (also important for suppressed fire)
    – Manufactured in the USA.

     


    IMPORTANT!! You MUST use the G4 Enhanced Cam Pin in the G4 Side Charging Uppers!
    Use of a Standard Cam Pin will cause the Bolt Carrier Group to lock up in the G4 Upper Receiver and be VERY difficult to remove and could damage the Upper Receiver.
