That style looks great, good job. I have been waiting "patiently" for the Monolith version and seeing this one makes me wonder why more people haven't tried to capitalize on bringing out more options for forearms, because the possibilities seem endless!
There is just not enough money in making many different versions.
I am not a person who likes rails but lots of people do. A company
would need to make a mold and stock every variation. I don't
think there are enough FS 2000's out there to be profitable.
