Biography
Through TacticalYellowVisor.net and online firearms communities, Sloyer developed a direct, analytical voice on rifle configuration, cyclic rate, parts specifications, tactical gear, training trends, and the wider online firearms culture. His writing reached beyond enthusiast forums; Soldier Systems Daily highlighted his “Moar” commentary on consumer behavior and performance in the tactical market.
Professionally, Sloyer is Vice President of Innovation & Strategic Services at KAST Construction. His construction career includes field-engineering, project-management, BIM, technology, and operational-excellence roles. KAST describes his work as applying practical technology to improve delivery of its construction services.
Key contribution: “The Chart”
“The Chart” provided an accessible, side-by-side way to compare AR-15 manufacturers, materials, inspection and testing practices, and configuration details at a time when that information was scattered and difficult to evaluate. It helped give the community a common framework for asking informed questions and separating documented specifications from marketing claims.
Professional assessment
Sloyer’s contribution was an early, influential form of community-driven technical curation. His practical, skeptical approach helped raise the level of discussion around rifle quality and equipment performance, while his later professional work reflects the same interest in making technology useful in real operating environments.
