This is a single pin sight extension, to allow the aperture or sight housing for a HHA Optimizer or Ultra sight to be further forward from the riser than the manufacturer's specs allow. Where most single pin sights have a short distance between the housing and the sight aperture, this extender allows the sight pins to be 2.5 inches forward of the housing, providing for greater accuracy and a greater 'tell' in relation to any riser torque.
Note: this may make a 0.010 inch sight pin appear very small. Available in black only.
