The Umarex GBB MP5 has full proper licensing between Umarex and H&K, it’s built by VFC which means that the weapons design and markings are spot on. The 30 round real cap magazines have a steep double stack making jams unlikely, if feeds Top / Green Gas / Propane gas. It also features an adjustable rear sight with four different settings and a classic hop-up. The gas reservoir is more than enough to cope with the cool down while emptying the magazine in either semi or full auto fire (classic hop-up). The main body and magazine are metal but the lower receiver / grip is all polymer like the real thing. this MP5A2 is 27.95in and 6.57lbs making it almost the same weight and size as a fully loaded real thing. As a metal GBB SMG, it also weight distributes similar to the real thing as the furniture is real and metal distribution is similar. It also kicks like the very best GBBR Airsoft guns out there. I had purchased this rifle about a year ago and have not had a chance to bring it out on the field and just recently I took its first shots to make sure its functioning (about 60 shots). It is brand new, in perfect condition AND HAS NEVER BEEN DRIVE FIRED!!! I have had it sitting in its original box for the past 9 months but just recently had to get rid of the box as it took up to much space. As of now it is wrapped up in a blanket so you can be sure that there is no chance for dust or and other sort of damage.
