Question for those using 9mm uppers on their FA guns. Anyone have egging problems?
I bought a DDLES 9mm lower that had a broker hammer pin *and* broken trigger pin in it. It had started to wear the receiver on one side of the trigger pin. That was from semi fire with a ramped bolt. It has KNS pins in it now and runs fine. If the pins had never broke I'm sure it would have been fine.
I have a friend that has a Colt SMG and it has had thousands of rounds dumped through it and it shows no signs of wear. /threadjack
