RAGE’s streamlined 3/4" dia., along with its HexFlat™ design, make it fly like a field-tip. The machined aircraft aluminum body features HexFlat™ design for stable flight, with a stainless steel instant-cut tip. The cam-deployed rear blades follow the tip without grabbing or deflecting, even on an angled hit, and are guaranteed to deploy before entry, maintaining full kinetic energy.
