Odin Works Adjustable Low Profile Gas Block - OK to use with Grendel?

[R2BRO]

Here is what i found to be interesting:
https://www.wingtactical.com/firearm-par...gas-block/

but this was alarming from description:
"*Not for use with pistol length gas systems and high pressure rounds."


I am planning to use it with 18" Grendel build, not a pistol, however; is Grendel considered a high pressure round? Can i use this Gas Block in my 18" Faxon build?

And IF it is OK to use, should i get clamp on or set screw version?

thanks.
