Yes the original KWA ERG. Has a laundry list of upgrades ZCI gears SHS Piston Double O ring nozzle M110 spring Swiss Arms 6.01 stainless steel tightbore Prommy purple bucking SHS High Torque Motor May have others but I don’t recall. I love the gun but can’t justify keeping it because I have a PTW which is pretty much the same thing. Only issue is it needs a new battery connector soldered in & also a buttplate for the stock or you could just swap the stock🤷🏻‍♂️ Shoots great & the recoil is a blast. Comes with 5 mags (will throw in more depending on price agreed upon) Two are erg mags with cutoff One is a regular k120 Two are just elite force mids Trades I would be interested in are MK18, CZ805 Bren, VFC guns, krytac guns, lmgs GMR stuff, Really looking for a WE XM177 gbb Don’t be afraid to offer up!
