Airsoft Canada - View Single Post - MP5 Mechbox unwinding ->lockup

I found my MP5 would have it's anti-reversal latch overrun (unwound when I'd stop shooting) when I bought a second PDI 150% spring and found it too long (6 5/8") and stiff compared to my original one. I cut off a few coils, installed it, the gears and piston would unwind after every few shots. I took the spring out, threw it as far as I could (waste of $20) and put my good 150% back in. Haven't had the problem since. Remember my pressuring you to get rid of that spring and buy a good (NON-PDI) spring that went through quality control?

See why now?
