Yes. You can have a Z-Grip Emag. You can also make an M-Grip Emag if you like. The only restriction is that you can not use the same Z-Grip Image used by Tom in his Announcement Thread.

Yes, you do your own milling, modifications, combination of parts/products, setup, etc.

Just follow the Official Rules... they still allow a WIDE range of things you can do, and more flexibility than most would need.

Hope this answers your question.
