ABSTRACT:
An archery bow sight having a plurality of sighting pins for setting range includes a plurality of pin receiving and holding blocks mounted in a mounting block that defines a path of travel for such receiving and holding blocks. The sighting pins are received and held by the receiving and holding blocks and move with them. Apparatus such as a threaded shaft and thumbscrew arangement is manually operated to move individual receiving and holding blocks along their paths of travel and to hold such blocks in position whenever operation of the respective moving apparatus is stopped. In this way, individual receiving blocks and sighting pins received therein are held in position unless positively moved by operation of respective moving apparatus.
