Setbacks and Hi impacts.
This came from Robin Oury. UE's owner.
There are very good tread on this on UE f.
Here are some pics! ( I don't have any crédit for the pics, just c and p here) Tk DigitalChaos.

Notice the circled area. In authentic arms this area forms a triangle, hugging the inside and outside the whole way unlike the almost oval/rectangle shape seen in fake arms
Notice the red shaded area, in real arms the level difference in this area is cut straight as opposed to curved in fake arms.
Also besides Setbacks all UE arms comes 100% polished, like it was carved rather then machined.
Fake
This pics is directly take from his store!!!

This pic may look like a dint or ding in the metel, but looking at the arm a little closer and it has pitting in a few spots. Witch is cheap alluminum. Also there's rounded shape instead sharp edge. Tk Will427
