You are a;; probably familiar with the SCOPYED Crossbow.
IN 2009 on YOUtube the is a clip of one.http://www.youtube.com/watch?v=rdtU9mflqx.
I found another clip on yuotube with a hunter in a tree stand shooting at any conceivable angle. The bow is light approx 100lb draw and highly manouverable due to it being so short and light. Can be fired from the prone pos.
Does anyone know anything more. I want to build one,
Ive never seen anything like it .
