I'm open to trades. Asking 450 shipped and fees, upgraded and will throw in extras. Mint condition Vfc colt trademarked lower. Internally it has a mosfet, 12:1 shs gears, high torque motor and other stuff I cant remember atm. I will include 1 PTS Pmag but it does not feed Pmags well. I'm selling this as all my other Pmags do not work well with it but my EPM and Stanags work well. I willl include a PTS Griffin armament SDII supressor and a Valken red dot along with some rail covers and other stuff. http://imgur.com/a/05lOC6A
