Hello,
I recently bought an ICS M4, with colt trademarks. And I bought a Madbull Daniel Defense Lite Rail 12 inches to fit on it.
I heard that this ICS version had metric thread so I jumped on it.

This is the rail.
I dismounted the handguard, front sight etc and when I come to install the Madbull barrel nut, it wasn't fitting at all. I was able to turn once and an half but no more. I didn't want to break anything so I stopped.
Looking at both barrel nuts (Madbull and ICS ones), the thread is quite similar to me, CCW for sure, but I am not used to see differences between metrics and imperials.
Is there a way to be sure that the ICS thread is imperial?
I saw the madbull barrel nut for G&P, maybe it could solve my problem?

I have no standard M4 receiver with me, so I can't be sure that the problem is from my M4 or the Madbull barrel nut.
Someone had some similar issue?
I am open to all suggestions!
I can provide pictures if needed.
Thanks in advance!
And forgive my bad english ^___^
