Typical thickness of a M-LOK handguard?

[338_Lapua]

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.

I've got a bunch of them, and while I've never measured I know the thickness varies considerably because when I'm swapping accessories the screws need a lot adjusting to go from one rail to another.

Good to know! Do you have any that are 2.5mm or 3mm thick?

Just measured 7 handguards randomly, they were actually all 2.5-3.1mm thick.
