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.
