The gun arrived in a sleek looking black box and already made a good impression on me. (note: those dents in the box were from me dropping it )
The interior of the box was lined with fabric that gave a look that just screamed quality. The gun is aesthetically pleasing to hold, not too heavy not too light, and it is fairly well balanced.
This gun has a metal slide but no trades. It does have rails for mounting lasers etc. in front of the trigger. The sights are fully adjustable and the gun has adjustable hop-up, so zeroing it in will not be a problem.
I have to report that the gun shoots quite well. I shot a man shaped target from 20yds with some friends at s4, getting 4 headsoths out of the ten shots I took the rest being neck shots. Im not the greatest shot in the world so this impressed me quite a bit. The bb's DID NOT curve to any extent that I could notice. This gun also has a good kick to it, adding to the realism.
So far I am very impressed with the Wei-e tech 5.1, I would definitely buy this gun again.
