[Kos-Mos]

I had an old (very first runs) M4A1.

To give you an idea, it is the first version, with copyright to TDS (Yes, the crappy brand). They where the guys selling the ICS rifles on the US market at that time.

I outraged some 400 fps guns when it was at 360 fps, and using .20.

I sold it to a friend and worked on it yesterday.

Part are quite easy to get, you can swap the whole upper (like he does) for changes in barrel lenght and FPS and the hop-up is similar in design to the ones used in G36s.

Always full metal.

In this particula case, we had to modify a KA bullbarrel to fit the hop-up properly, but nothing extreme.

Also had issue fitting a KA Knigth Armaments RIS, but for some reason it fitted perfectly on a KA Troy CQB receiver. Installed the KA Troy RIS on the ICS instead.

If I ever buy an AR again, it will be an ICS.

People complain about the split mechbox because they think that the alignment is not good.

I can tell you, if you assemble the gunproperly, the assembled mechbox is rock solid.
