The hostage (reg) is around 39.00 It only contacts the shaft at 3 points 3 O'CLOCK / 6 O'clock / 9 O'clock The pro is setup the same way but is a alloy frame @ 89$ the (reg) hostage is made of a glass filled extruded polymer (glock frame fame) and is indestructable so far. A 5 to 9 fps increase over the WB and proven quieter. It is part of the newOctane line up from Bowtech/Diamond.I dont believe they would buy out the company that made it on a whim. I am sure it is a tough, capeable rest.
