Abstract: An improved archery target sight, in which much of the unneeded weight present in support arms is removed. This sight utilizes a pair of lightweight rods, that are positioned lengthwise vertically to each other, and where the rods are gripped between a mounting block and clamp, with the rods placed in recessed grooves defined in the block and clamp. The rods extend outward from the bow to hold and position vertical adjustment sighting apparatus. A stop block may be attached along the length of the rods, where the stop block is adjacent to the mounting block and provides a means to set the placement of the rods in reference to the mounting block, by consistently placing the stop block immediately adjacent to the mounting block, so as to allow disassembly of the rods from the mounting block, and reattachment at a later time with an identical configuration achieved by repositioning the stop block against the mounting block.
