CAA Licensed Airsoft AEG Rifle by King Arms (Model: M4 Carbine Black)

"overall this gun was pretty good. the price was pretty good. About two months after I bought it, I started having problems with a wobble stock and rotating barrel. I barely used the gun in those two months and it had some major issues. Not sure if I would buy it again. But every time I called Evike, they were pretty helpful in finding a solution. Good company, just bad product.

Cons:
wobbly stock
rotating R.I.S
the accessibility to the battery is very limited
no rails on the top front of the gun
no instructions on how to tighten the screws and where they were on the gun
the magazine cant be fitted with a Magpul
the delta ring would often slide on and off of the barrel which presented a problem, though I usually just wrapped some leathery tape around the barrel and it would be fine.

Pros:
very cool stock
very cool flip-up iron site
comes with a speed loader in box
fairly good price
shoots very far
light and agile
the option of putting long or short rails on the bottom of the barrel

"Not bad for a starter gun, wouldn’t recommend it though.
Pros:
Great bargain, gun is almost ALWAYS on sale for about $100
The mid cap it comes with is amazing, never had a single problem with it and holds around 150 bb’s

Cons:
Doesn’t shoot very accurately or far, more of a CQB
Fire rate is kind of low
Cheap plastic
Annoying battery holding in the empty barrel space
Comes with a mid cap instead of a high cap
Iron sights it comes with are terrible, they look nice but are ineffective
Only lasted me about maybe 50 hours of service before breaking

"I was very surprised with this rifle. It’s not quite like any other I own. It’s far lighter then I would’ve ever imagined, though some people may see this as a pro I do not. The gun is so light that it feels flimsy and feels like it would break easily, just about everything on it except the gear box is plastic. The plastic is polymer according to the description, but I’ve got other polymer guns and this feels far less durable. The battery that was suggested doesn’t properly fit in the gun like advertised. As well as most of external parts are unique to this gun only, meaning it’s very hard to get replacement parts or upgrades. See these wouldn’t be a problem with this if the price wasn’t $150... you’re basically just paying primarily for the licensing and just a bunch of plastic. You could get yourself a much more solid and upgradable gun for the same price or even cheaper.
But overall the performance of the gun is meh. I’ve run into a few feeding issues but that may be just because I tried to relate the hop up. (You decide whether that’s a good thing or not). The guns shoots around 400 FPS (which is good)with a 7.4 nunchuck lypo, which is the only battery I could find that could fit inter hand guard. While shooting the gun on semi the gearbox feels very slow and sloppy and would often times jam when I tried to fire lots of shots in rapid succession. Fortunately full auto is pretty smooth. If you use this in a competition I’d use it in short bursts over semi to avoid the jamming issues.

"Decent rifle, poor construction, bad customer service. Within just a few normal field sessions, the plastic barrel nut that threads onto the upper receiver had broken, and needed to be replaced. This barrel nut seems to be unique and can't just be bought normally and isn't sold with any of CAA/King Arms' handguards. I emailed both CAA and King Arms, but never got any response. As of now this rifle cannot be put back together properly, and is worthless

"First of all this gun arrived in a damaged package. When I opened it up the first thing I noticed was the front sight was broken off. Was pretty disappointed with that. Took it out on the field the next day to test it out worked for about 2 minutes until the gun just flat out stopped working. This problem persisted even after changing the batteries, switching fire modes and mags. At this point, I can only guess that this is a problem with the gearbox as there was no round stuck in the chamber. Overall was very disappointed and would not recommend buying.
