Typical thickness of a M-LOK handguard?

Anyone happen to know the typical thickness for a M-LOK rail?

The only source I could find online said 1/8 inch thick, or about 4mm in the description.

That seems a little thicker than I would have expected. Generally they appear to be around 3mm from what I've seen.

Unfortunately I don't have a specimen handy and the M-LOK specifications don't seem to specify the thickness anywhere.

If anyone could put their calipers on one and check I would much appreciate it.
