Does anyone know what material and/or heat treating (if any) is done to a standard bolt catch?

Or has anyone tried drilling/tapping into the bolt catch pad for a custom setup?

I'm looking into making my own BAD (battery assist device) like that in the Magpul Dynamics DVD since there aren't any out yet.

Thanks.
