Yes, I am fully aware of that. They simply resell products made by other companies. That being said, some products they repair and some they don't-that's where you have to be careful. This was my first air soft gun purchase and as mentioned earlier, it's a POS!:( Mind you, I made my own air gun spring compressor, rebuilt pellet guns, have my FFL C&R license, rebuilt several C&R guns (including Enfield SMLE Mk 1 and M1891 Mosin-Nagant) and perform hospital mnt, for a living.
I easily disassembled and reassembled this AEG. The gearbox and motor are in great shape! There is no wear in the gear box, nor any debris inside it. BUT, the motor is spinning LOOSELY on its drive gear that moves everything else! It's simply a press fit gear that stretched on the motor shaft! I'll bet I didn't put more than 500 rounds through this gun! I have much cheaper AEG's that are still working. At least the single action spring power still works. Selling this gun for what I can get for it.
I did send my findings back to Umarex for grins and giggles. Stay away from this gun!
