"I bought this gun for $150 and this is about how much its worth IMHO.


Good Looks

Tight Barrel

Metal Hopup

Controls for left handed players


Cheap Gearbox, not a single drop of grease anywhere.

Plastic Guide Rod

Cheap Motor

Cheap wiring and trigger contacts.

I bought this gun along with Matrix Pro Line, and this is has much cheaper components. Ok gun for $150 not 300$ quality of KWA

"I ordered this on the 24th and it got here on the 2nd. It is a great gun, full metal construction and heavy. The orange flash hider it comes with appears to be glued but with a wrench, I managed to get it off and attach a silencer. Remember it has negative threading. The only problem I've had had been the magazine. It wobbles up and down and has to be pushed up to feed correctly. I fixed this issue by putting two strips of electrical tape on the sides of the magazine. Although the magazine is a little hard to get in and out, I would say that this flaw is only minor and it has an easy fix. The buffer tube, where the battery is supposed to go is very small and could not fit my battery. I managed to find another place inside the stock but it cannot adjust all the way. I gues that was my fault for ordering a big battery. All in all I would rate this gun five out of five. It shoots fast and sounds awesome.

"This gun is amazing! Its got a great rugged feel to it. Very sturdy!
I was able to score this beast when it was only 150$!! Ive put a 230mm mock suppressor on the end to help protect my extended tight bore. It can be a CQB M4 if you need it and can easily be upgraded to a DMR style M4. (My personal taste)

Fully Metal
No rattling or vibration.
L/R handed compatible.
LiPo Ready! (11.1 1100mAh fits good)
HQ scratch resistant Multi cam finish.

The firing mode selector switch is made of plastic and doesn't click into place like your clasic M4. :( Its the only cheap feeling part on the gun.
The mag provided is metal, but it rattles and is a bit loose in the receiver, may just need to try a different brand.
