View Full Version : spring problem

06-27-2004, 07:35 PM
I just got a new spring for my gun, however, I am wondering now if its the wrong type, the original spring had (circled in red) a funny extending thing that was supposed to fit into the notch (circled in red) on the metal part.
should i go ahead and put the spring in? Its a systema 120S so it should work right?

What kind of gun do you have? Is it CA? If so I believe you take that spacer out when installing a upgraded spring, I could be wrong though...

the gun is a TM MP5, do I not use the spacer with those too?

That "spacer" is actually the part that the stock piston head screws into. If you did not get an upgrade piston head, you'll need to install that piece back into the piston to the little nub you see just under the red circle extends into the small hole in the front of the piston. Then, you screw the piston head back into that piece. That spring will work just fine.

Make sure to put loctite on the screw for the piston head too. The odds are good that it will back off if you don't.
