The Armortech Hunting Sight was voted best buy winner, from Inside Archery Magazine, its very first year on the market. The windage knob features 20 clicks per revolution adjustability. To move the individual sight pin up or down, turn the micro adjustment knob. The sight pin pivot lock is engineered to not vibrate loose. Do not over tighten or damage will result. The engraved partial ring at depth of sight pins is designed for greater accuracy when viewed slightly off center. The Armor fiber technology provides 100% protection to fibers that are fully enclosed inside tubing. Includes a Mathews Harmonic Damper.
