*ABSOLUTELY NO TRADES SO DO NOT ASK* This is the EMG SAI GRY in grey that is not stock except for the body. It has the stock barrel cut for the SAI Carbine version, it also has the prommy purple bucking and nub in it with a Prowin hop up unit. The outer barrel is the SAI square tapered outer barrel, (yes this is an aftermarket part), the gearbox shell is a lonex 8mm shell with a normal spring guide due to the buffer tube screw being so long. The GOMU unit will be included along with the grip and your choice of T1 or Holo sight. The stock is the PTS big battery stock. The engine is the P* F2 with the GOLD LOW FLOW POPPET (saves on air). The trigger is a retro arms flat silver trigger. I have 7 PTS mid cap mags I will throw in for $50 more. Shipping is on you.
