G&P Mk18 licensed by Daniel Defense. Features the new i5 gearbox and a quick change spring. This will not function with anything other than a 11.1v battery just FYI. I currently have a Prometheus tbb and prommy purple bucking. The only caveats are that this unfortunately cannot fire in full auto however has an excellent fire rate in semi (something must have shorted out for full auto to not function) and the rail system has some wear and scratches on it. I am accepting any working AEG VFC scar H trades. Price is shipped.
