The hell are you talking about?
You can replace it with ANY mag release you want.
I have used KA, TM, CA and G&P on my ICS... it works.
The ONLY parts that are not compatible:
SOME buffer tubes.
SOME delta nuts.
I have a JG/TM/CA/ICS hybrid that is based off a JG mechbox... has an ICS front-end, TM body, CA internals and JG stock.
