Black Gold Sights are made to hunt. Their “BombProof” pins are fully machined from aircraft grade aluminum. All sights feature sleek, sturdy bases with oversized clamping dovetails. When most sights fail, it is the pins that break first. Black Gold sights feature BombProof Micro Groove pins that are 30 times stronger than competitor’s imported cast, turned, or tube style pins. The Micro Groove technology protects the fiber along its entire length. These are the toughest pins ever built on an archery sight.
