How to fix your spring airsoft pistol with tutorial

This is a very quick and easy way, it may have been a little bit dark but once you see the internal of the gun you might play around with it if you didn't see it clear enough.
STEPS:
1: Rip the top part of the airsoft gun off ( The thing where you cock it back.)
2:Take the front spring off and then the other spring where the the spring is half in the that plastic thing. To do this you must cock it back just like you would if you had the plastic thing on but don't let it go instead pull it up and it will come out very easily.
3: Melt the plastic piece that fell off onto the opposite side of the thing I pulled out. IT MUST BE STRONG IN ORDER TO MAKE IT LAST A LONG TIME.
4. Put everything back together (Do your these steps backwards besides steps 2 and 3.
