G&g knights armament SR15 - for parts or repairs

Took this out of storage recently, and it doesn’t work. No idea why, I’m not particularly good at troubleshooting these. I did try couple different batteries though, so it’s not that.

Overall this looks nice, and hasn’t been used much, if at all. Very minimal wear. Aluminum receiver, ambi controls, feels quite close to real.
So if you have some spare parts laying around- this could be a good project for you.

I am located near Metrotown if you want to drop by and have a look.
