"I bought this as my second gun and I must say i was pretty impressed by it! Handles great and can get some great range. Full metal is great. Only problem is that the motor height and and hop up were a bit off but that wasn't too hard to fix. Highly recommended this gun.

"This gun is all metal, all metal gearbox, all metal rails, all metal gears, all metal upper and lower receiver, and so on. this gun is amazing for beginners or others who want a gun to upgrade an m4 for the heck of it. tearing the gun down is straight forward and not too difficult. only problems i have had with the gun are small springs breaking inside of the gearbox but i think that is due to how aggressive I am with the trigger at semi-auto. the trigger spring and contact plate return spring broke but they are cheap and easy fixes. i replaced the motor right away due to trigger response being a but slow and ROF is really poor with the stock motor. I personally replaced my motor with a Classic Army 25k motor and it performed amazing and gave me a solid 18 RPS. after a few months i have put a 6.03 madbull inner barrel, a lonex a-1 titan motor, and shs 13:1 speed gears and i am using 7.4v and 11.1v lipos.

all metal everything
great fps (around 375 with .20g bbs and after a little bit of full auto play with a 9.6v battery.)
comes with a reliable hi-cap magazine (also metal)
good accuracy at semi auto
keymod rail is beautiful

stock motor sucks.... replace it.
hop-up at full auto is all over the place. litarily.

So in conclusion the gun is great for beginners who want a solid gun for a good price. i recommend it.
(this gun isn't as good as a G&G m4 mod-0 but its all metal...and its a carbine rifle. so yeah.)
