SRC SR4 problems?

[rclementew]

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.

Did you do the upgrades or someone else? You should expect a louder sound after upgrading, but if it's making a higher pitch sound (before the piston is released) and gears are locking up occasionally, then it's probably a bad shimming job.

It sounds like it needs to be reshimmed, and the motor plate needs an adjustment. Bring it by the Phoenix or Scottsdale JT and we'll look at it.

thx, ron.  jeremiah fixed me up good.  It sounds a little better but we determined the systema gears just make that sound.  Also, after jeremiah opened her up and put her back together, the gun hasnt ceased up since.  Thanks guys.
