Guys, my e1m28 was being dead for 3 years inside it's bag , until now!. I has already the JJ-airsoft PDI zero trigger clone on it But I never could make it work because I don't have a propper 90 degree piston, so what I did is just take the stock 45 degree piston and carved in to a 90 degree...

I have a vsr11 sniper that is slamfiring. The piston is metal and doesn't look to worn. Neither do the sears. What else could be wrong with it?
