Awesome gun!!! Just got it and it shoots amazing!!! Fires 450fps with propane and is great in summer outdoor games (gas mags freeze up in the cold) put a good lot of bbs through this thing And only one part has broken so far.

Pros:
Realism is pretty awesome. Turns heads
Build quality is great (its a king arms what do you expect?)
Blowback is very realistic
Fps (great for outdoor use!!)
Accuracy

Cons:
Broke loading nozzle! (Get a g&p one when you get this rifle)
Mag freezes up in cold (all gbbs have this problem)
Mag leaks a bit (get the regular g&p or the 39rd pmag! They are much better!)

Ammo capacity isn't that big of a deal for me. Overall a great gun and is King Arms quality!!

i bought this gun about a year ago now and i have to say that if you are a newbie to gbbr then this gun is for you because out of the box it is great. if you are more advanced i would recommend the g and p woc because it is way better but requries some knowledge as the manual is a fail and doesnt have everything you need. the only major down fall isnt even the gun its the mags. for 5 dollars more buy the g and p mags and save uself a lot of trouble

The King Arms M4 GBB is my first GBBR, I had some experienced with gas guns from my Tokyo Marui Glock 18C. GBBs are so much more realistic than AEGs with the kick (AEGs are boring). I have installed Daniel Defense Omega X 7" and real steel ACE stock. I recommend switch to WA/G&P system, get new bolt and mags.
Pros:
Full metal
Colt trademarks
GBB
500 FPS ~ 300 FPS (adjustable)
ROF is adjustable
great kick
Compatible with real steel parts (externals only)
Cons:
I accidently stripped the threads (14mm +) on mine
I've had 3 Magazines, all leaks and reject gas
