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

    Incredibly beautiful work, so smooth, fine craftsmanship really went into this design. Applause to you, Gibbz! Wow! Far exceeded my expectations.

    So far I’ve built 4 Rifles and 1 pistol using the G4 Side Charging Uppers. In each case I’ve chosen the latching side charging handle. As an engineer myself, I really appreciate the strength of this design as well as the tolerances, attention to detail and overall craftsmanship of this product. I can’t say enough good things about it. And best of all, the Rifles I’ve made are the envy of all my friends. They shoot and function perfectly. I especially like the ability to charge the weapon without taking it down from my shoulder, always keeping my sights on the target. I just received (2) G10 receivers for 308 builds I’m planning. I just unpacked them and they are the same high quality I’ve come to expect from Gibbz. Keep up the good work guys.
