This invention can slide open to accommodate most brace heights. This invention aids in the bow and arrow tuning process. The sliding tubes may have a rail and raised guide channel attached to prevent turning. The smaller diameter tube may have a raised rail its entire length. The larger diameter tube may have a raised guide channel its entire length to allow the small tube to slide open without turning.
