Primary Arms has promoted Robert Sheets to vice president in charge of optics engineering while that division expands. As director he had already enlarged the engineering staff, directed work on new optical products, and cultivated partnerships with premier suppliers in the United States and other countries to keep quality high.

Sheets will keep running the optics engineering group, partner with product developers to match projects to customer and market needs, and advance reliability along with fresh ideas. President Matt Fleming described him as a skilled engineer who will steer the team toward products that perform well.
