||After I've had my ICS M4 for a year now, I'm surprised it is still holding up as well as it is.
To start of, I am going on the outside.
Looks and Feel
The body is aluminum with the barrel being a steel alloy. The body is very sturdy, but not quite as nicely detailed or refined as CAs. It also has a problem accepting some mags, I'll get into that later. The ICS has the best outer barrel on any M4 model, it's very big and super sturdy. Barrel wobble is non-existent.
--The furniture is horrible looking, it has a shiny "plasticky" look to it. (A nice coat of flat black paint fixes this)
--The hanguard is slightly thinner that TM's or CA's, and if you adjust the barrel for a tighter handguard fit it won't move at all.
--The pistol grip is much nicer feeling in my hands because it is thinner to better simulate the real one.
--The 6 position LE stock is good, sturdier and tighter fitting than TM, but not as tight fitting as CA.
--The forward assist button now has usefullness to it, it release the spring tension.
--The detatchable carry handle/sight has very smooth adjustment and elevates slightly more than other brands. And it isn't loose or wobbles.
--The paintjod is the best paintjob on airsoft gun I have ever seen, it does not chip, flake, or peel and scraping or sanding it off is no easy task either. It has a somewhat parkerized, dark gray-blueish tint to it, it is not light gray like it is in the pictures.
--The threading is the standard 14mm CCW
--the reciever has been stretched by about 1/4 an inch to accomodate the split gearbox easier.
First and foremost ICS has the most user friendly gearbox ever. I love the split garbox design mainly because it helps to alleviate some of the problems that plague V2s. It alone, fully assembled, weighs almost as much as an entire Marui gearbox, fully assembled. The upper gearbox has the spring, piston, cylinder, etc. and pulls out very easily so you can change springs quickly. The gears, switch, etc are in the lower half.
--The switch is PROBLEM 1 of 2, the switches walls are very thin and just don't look high quality.
--The wiring is a small gauge wiring, but it does the job very well and is very high quality.
--The motor (Turbo 2000) is horrible, it sounds funny and smells funny. It is starting to kill over on me now. It is PROBLEM 2 of 2.
--The barrel is supposedly 6.08 but it looks smaller, maybe 6.06-6.05.
--The hop-up is so far the simplest one yet, it has one big wheel that is very tight. I wish some made a metal one, it is Marui compatible.
--The gears have only slight usage on them, and the have fired 10,000 through them now. So putting 2 and 2 together they must be rather sturdy.
--My piston is needing replacement now because there is a slight leak, my fps has dropped to about 300.
--The selector is the smoothest and most realstic I have ever seen on a replica.
--It performs equally to that of CA. The funny sound the gun makes when firing sounds like it has a suppressor on it.
--It is very accurate and with a 9.6 v battery, fires fast, about 900 rpm.
--The problem in performance comes into its feed. It is very picky in magazines. The mags that work the best are G&P, Marui, MAG, and ICS. The mags that don't feed so well are STAR, CA, and 2-Roy.
The best way to fix the feed problem is to put a small piece of duct tape little "nitch" at the back of the mag well.
I find this more to my liking than either CA or Marui in terms of Armalites. The AK74 produced by ICS is a different story. It is a good overall gun. The newer models have a better switch and.....supposedly, a better motor (Turbo 3000)..... I still prefer the Marui motor.
The older models are harder to upgrade than the newer ones. The new ones now can take an upgrade as easily as any other brand.
It is good for veterans and experts. I wouldn't refer it newer players.
The gun needs some serious fine tuning when you first get it, which is only a problem if you don't know how to do it.
I now have the 2006 model and it ROCKS!
I have upped them bothe to 370 and replaced the motot in Lara (2005 model M4) and put an ACOG on Amy (2006 model M16)
