I started having problems with my G&G GR-16R4. I had the wires and the battery tested and had no problems with them. It was discovered by my coworker that the safter switch was lose. If he held the triger down and moved the switch back and forth slowly it would fire at one certin point. We could not take out the pin to get the gear box to come out. I was going to send it in to AXE but I dont feal like spending 30 and hour for repairs. I spent $500 on the gun and really liked using it. So I was wondering if anyone knows of a fairly priced place to get it rapaired or if anyone knows how to get the gearbox out of this gun.
