This gun was given to me by a family friend and I have no use for it. It has minimum time being used so it's still great quality even though it's an older model. The man I got the gun from, Matt, told me he had made the gun LiPo ready and it can use 11.1 or just a normal butterfly type 9.6 or 8.4. The gun shoots really well and is very accurate however I believe the hop up is messed up because even with it all the way down BB's are still curving up a little sooner then they should be but that should be an easy fix for anyone who knows how to change a hopup and for CQB fields it's almost not noticeable especially if you use .25 or higher BBs. The gun also comes with a working 9.6v battery and a high cap magazine with a magpul grip on the bottom. Mag fits well and feeds fine. If you have any other question feel free to email me! NO TRADES! Looking for cash only, best offer.
