The Dead Nuts 2 Supreme employs Copper John’s proprietary Bright2 Technology using extremely durable .019 fiber optic material that allows for maximum transmission of light through the efficient use of both ends of the fiber and overall fiber length. This 100% machined aluminum sight has a vibration absorbing fiber carrier offering exceptional shock free performance and fiber protection from tip to tip. If that’s not enough to set this sight apart from the pack, it also has 2nd and 3rd axis adjustments so the archer can make proper use of his/her bubble level. Finally, the Dead Nuts 2 Supreme has micro adjust capability on both gang adjustments, each individual pin, and on the 3rd axis adjustment.
