I recently had a systema m120 spring and some systema gears put in my SR4 and it is making a much louder and obnoxious noise when i shoot. When I hear it I think it could simply be that the new gears are louder but something just doesnt sound right.
One thing I think it could be is the motor gear has worn a little and that could be causing the noise. It could also be the motor plate isnt adjusted right.
It is also occasionally locking up. I can feel that the motor is getting power, the motor just doesnt turn the gears.
I dont even know if i have a problem, it might just be the fact that i have newer and supposedly louder gears. Can anybody think of why my gun would make such a drastically different sound while firing (especially during semiauto mode) Thx.
