Another vote for sword. Made of much better materials than copper john's dead nuts and the pin tracks won't marr or be damaged from tightening the sight pins. All swords come with a light as well as long fibers so they collect tons of light and are super bright. The twilight hunter is a great no nonsense hunting sight, and the Apex 3rd plane is great for hunting and 3D use with a movable sight extension bar and 2nd and third axis adjustments.
