Not sure who the maker is, but they are decent bows. I shoot leagues with a couple guys that have them. Shoot nice and decently quiet.
I'm pretty sure they are made by diamond. It should say on the bow if so. I have one of the Bass Pro Shop brand (Redhead) bows and the Diamond insignia is next to the weight/draw length. I looked at both bows before purchasing and seem to remember that they were the same bow; both made by Diamond.
