Was given to me in a trade, not interested in AEG's. This is a G&G MP5 A5 with the blowback feature which is discontinued. Shoots great, tried with a 11.1 lipo and had no issues. Will come with 1 cap mag, 1 Lipo battery. For extra $20 will throw in smart charger for Lipo as well. $150 shipped and no trades.
