CASV kit should fit just fine. You don't even need to remove the rear handguard ring or barrel nut. The CASV upper fits right inside the collar and the top attaches to the flat-top rail.
King Arms CASV fits real steel, Systema, ICS and G&P that I've tried. No issues, other than the strength of the weld-spring on Systema and real Bushmaster ARs.
