Our G4 Uppers come standard with a hard anodized black coating (MIL-SPEC MIL-A-8625 Type III).
Upper not compatible with hand guards featuring anti-rotation tabs without modification. *
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.
Stripped version only. No FA or dust cover
We decided to take two approaches to improving the retention of our charging handles. Goal with one would be to improve retention but keep the cost the same. Goal with the other would be to design an new system that mechanically locks the handle for ultimate retention. Success !! Here is a breakdown of the two different handles.
Gen 2 Handle
- Size of the detent increased and optimized for Gen 2 detent pocket
- Offers much better retention of the charging handle
- No increase in cost
Gen 3 Handle
- Latching Handle provides rock-solid retention of the charging handle during any conditions.
- Easily unlocks when pressure is applied to the front of the handle.
- $40 upgrade option on all of our side-charge uppers.
