Hi,
I recently bought this gun (G&G GC16 Carbine) on this forum and when I was dissembling it I noticed it had a different stock base thing (sorry I don't know the technical term). It's silver and has a threaded bit towards the receiver body but then a larger circular bit with guides on the side. Because of this I'm having problems rewiring it and removing the spacer so I can put on one with a sling attachment point. I've attached a picture so what I'm describing makes more sense.
Does anyone know if this can be replaced or am I stuck with it? There's also some residue from glue or something where the stock base meets the receiver's body if that's any help.
Thanks in advance.
