ICS CXP-15 Free Floating Rail

[Paul55]

Hi

I have an ICS CXP-15 Pistol with the latest keymod rail. The problem is that you can't use the keymod slots as there is no clearance on the front block. Pics show the problem.

How easy is it to fit a free floating rail system on one of these? Are ICS compatible with most barrel nuts out there?

Thanks for reading.
