I am looking to buy a kwa m93r off my friend and he does not know if its the first one without the ns2 system or the one with it. Is there any way to tell the difference and what are the differences?

I believe if you take the slide off and slide the gas nozzle forward, if the rubber seal is green it's NS2. If the rubber seal is orange, then it's NS1.

The difference between NS1 and NS2 is that NS2 gives you much better gas efficiency, as you do not waste as much gas as you would with a normal other GBB. Also, there is usually an FPS boost given the better seals in the NS2 system that create a tighter seal that allows the gas to travel from the magazine to the nozzle and from the nozzle to the bb better, than an average GBB or NS1 system gun.

If you can get a picture of it, post it here, that will also help us determine which generation it is.

That would be the NS2 model.

Actually, the easiest way to tell NS1 from NS2 is to look at the nozzle at the end of the cylinder.  If it is silver then it is NS1.  If it is black polymer then it is NS2.  NS2 systems have used various sized cylinders over the years and therefore various sized, and different colored, o-rings.  When you see a green o-ring it is a 15MM cylinder.  When you see an orange one it is 14MM.  An example of the changes that have occurred in one gun would apply the to MP9.  It has had both cylinders and therefore both the orange and green o-ring.  Most recently it has come with the orange o-ring.  This is an improvement because the 14MM cylinder is actually thicker and therefore more durable...at least in the MP9.  To cloud the issue, the first generation ATP (NS2) actually has a black 0-ring....that's another story though.
