"Received it with a broken air nozzle. Would seem that a "basic" inspection would be a good idea prior to shipping.

"I just received mine today and it seemed fine until i inspected it some more.

front wired for mine

Air nozzle was cracked

and the micro switch was caught up in the gear set

"The wires are not even the right length to fit into the stock, the clear part in the photo is under the gear box thats how short it , and it will not fit into the M249 body, its also not the same one in the photo.
