About Product

True friendship and brotherhood comes from Warriors that fought and died together in combat. It just seemed natural that these friends decided to start a collaboration between three great American companies. Therefore, the “KRUS” was born. Three Former Longbow Apache Pilots Collaborated, two from Kryptek and one from Spike’s Tactical, to develop a great AR-15. We looked for a trusted optics company Leupold and Stevens is that company. We rely on them with our Trophy Mounts, Targets, food and our lives.  The “KRUS” is a thought that only the team of Spike’s Tactical, Kryptek and Leupold could develop.
