The bow you have is, with minor differences, a Ross Cardiac. The Ross Archery company used to contract out the manufacture of risers to G5/Grace engineering. At some point, Ross was unable or unwilling to pay G5 for these pieces and G5 was left holding a bunch of parts for Ross bows. So, in order to recoup their investment, G5 made bows out of these parts with their own name( Quest) and marketed them. Since then, Ross was bought by Bowtech. I've never seen a Quest bow but I assure you that it is a quality bow because Cardiacs are one of the best shooters on the market. I'm not certain if G5 intends to continue making bows of their own design once the Ross pieces are assembled and sold. It also remains to be seen what will happen to the Ross designs with Bowtech buying them, but I've heard good things. Anyhow, you got a shooter, good luck with it.
