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.
I was under the impression that none of the controls were compatible. I guess thats what happens when people like me speak up without first hand knowledge and spread misinformation. I retract my post above and do apologize.
