Virtually New Kwa Tk45c Shooting Burst/Full Auto on Semi

[chipsngravy]

I just picked up a second hand tk45 which was unused, still has the tag on it and everything. I had a video from the guy of the gun shooting fine however I’ve just tried it out for the first time with the battery he sent with it and it’s shooting 2 round burst on semi, occasionally locking the trigger pull as if it’s on safe, and even shooting full fledge full auto. I’m using an 11.1v which is recommended by kwa and have tried both with and without the mag loaded with bbs
