The Axcel Achieve XP Pro Compound Sight is designed for the top archers in the world, providing unmatched precision and stability. Featuring a new ultra-high modulus carbon bar that is twice as strong with thicker layers of carbon, this sight offers superior strength and durability. The patent-pending wedge lock bow mount bracket provides a stronger hold than any other, while the in-line tension adjustment ensures the sight pin stays on target from shot to shot. With a stronger 10-32 windage lead screw, enlarged diameter windage and elevation knobs with click locks, and a thinner, weight-reducing elevation rail, this sight is engineered for peak performance. Included are sight tapes in yard measurements for precise adjustments.
