Selling my 552 Commando as I no longer use it. Has no mechanical or wiring issues and has a fairly consistent fps between 365-370 with .20g bb's. Comes with 2 highcaps, 2 batteries and foregrip. Threading is 14mm- like most airsoft guns. Sights have glow sight paint so they are easier to see and slightly glow in the dark. If trading, No M4's, AK's or High capas please
