This is the newest addition to the Double Eagle Metal Gear Box (MGB) AEG's. DE is providing good quality AEG's at very affordable prices and this UMP is no different. It features a solid ABS plastic construction with fully functional charging handle, all metal version 3 gearbox, and metal hop up. This is a great airsoft gun for CQB because of the folding stock and rails on the front hand guard and the top of the upper receiver. For $129.00 this gun comes complete with a high capacity magazine, battery, charger, goggles, and sling. Also, since this is a G&G clone it is compatible with G&G UMP magazines! If you are a fan of the UMP but have been waiting for someone to make a good working version of it then this is the one for you.
