Bought a Pyramid Trigger in September, took it out and it was shooting FULL auto! I called them and they told me to adjust the trigger and bend out the conncetor and thatll do it. I tried adjusting and still no luck. I took a ghost connector and installed it and seemed to help. I called back and they sent me out a replacement connector. I put it in and it was still double tapping. I called back and they said for 40 dollars plus shipping, send the complete gun to them. I did that costed me 140.00. I got it back and the notes said they replaced the mag spring and ghost connector and cleaned the already clean gun. I took it out two days later and STILL was double tapping. I called them for a full refund and they said that they refuse to give me a refund. and whateve happened between them shipping it and me shooting it was not their responsibility! avoid buying anything from them !
