Submited By: German S. on 06/12/2010 This product is not as good as it looks, for me it wasn't, i was expecting a thick piston head with a thin o-ring, but it was the other way, the first 500 rounds that i used my gun with this piston head, it crashed into pieces so i got to put back the stock piston head.
Maybe my mistake was the M120 spring in my gun, but next time i'm going to buy aluminum parts. | |
