Installing new spring?
Hi, My field is indoors and has a 330 limit and my gun is shooting about 360 so I wasn't allowed and had to rent a gun so I ordered an s90 spring from airsoftparts.ca. It's gonna be here in a few days and I was wondering how do I install it? I added a new bucking once but I have no other upgrade experience. Finally, do I need anything other the spring.
Thanks
PS: my gun is a G&G MP5 SD5
