I’ve been looking around many websites for a long time for a battery for my G&G UMP 45 for a long time. Because of the small compartment size, it was very hard to fit a well rounded battery inside. Finally there’s a perfect battery for my gun at a very generous price. I just want to say thank you from me to all of you at zero airsoft for bringing my battery within a day. Very reliable, very generous, would definitely recommend!!!!
