Parts not cut to spec - TRYBE Defense AR-15 Mil-Spec Complete Lower Parts Kit w/Ambi Mil-Spec Safety Selector

I absolutely hate writing bad review but this needs it. This was purchased because of the ambi safety. (Which by the way, get a 60% throw safety or if shooting left handed the safety will cut into your hand. A 60% throw safety fixes that problem) After installing the takedown and pivot pins, they were very difficult to move in and out unless you used a screwdriver to break it loose. This is totally unacceptable for field use. The detents were drilled too deep basically locking the pin in the full in position. The last part I installed was the ambi-safety. After install and rotating the safety to the safe position, the safety would not move from that position. It was essentially locked in the safe position. Once again the detent was drilled too deep. What good is a safety if you can't fire the gun. After calling to see if I could get a new safety, they said I had to return all of the parts, not just the defective parts. Wow! Now I have to completely undo all of the work I just did. Keep the $$$, I Will never buy Trybe parts again.
