They had the Discovery first. They were cast risers, but in not so close pics, looked somewhat like machined. They had 3 bows that I'm aware of. The Discovery, the Intensity (both cast risers), and the Colorado, which had a machined riser. I got the Discovery when Firebrand was offering to send you one for 10 days, and then you could send it back if you did not want it, which is what I did. Not a bad little bow. Very low recoil and pretty quiet. Lots of system friction and a late peak to the draw, which is why I did not want to keep it.
