I was reading some things in the AEG solutions section and realized I didn't mentioned that. It makes the most subtle struggling winding noise as I mentioned and then silence. In full auto or semi there is nothing, switching between them results in no change. I thought at first that something was broken inside, but as I said I've noticed no broken or cracked pieces and it works great when I put it back together and in the gun for those first shots until it locks up on the last one shot. Thats something I should specify aswell is that the struggling noise is for the last shot, two at best and then just locks down.
I'm going to try cleaning the contacts for the trigger and battery points as suggested here by CDN_Stalker:
