Does anyone know if the Front MBUS sites will work on a railed gas block like those on Armalite's M15 carbine's or will it only mount on a railed free float tube?

Just wondering about height differences.

It will work, but in the instructions it says that it is not to be mounted on a gasblock because of the materials used to make the MBUS. Hot metal and plastic usually don't mix to well.

And most gas blocks are not tall enough anyways.

I hate to be THAT GUY but a search would have turned up the other 30 threads on this subject.

Thanks for the info.  

Search-fu must be weak, I did not find much in the Industry section on Front MBUS info.
