Primary Arms promoted Robert Sheets to vice president of engineering so he can run the optics engineering division during its expansion. Sheets had been director of engineering, where he grew the team, guided new optic designs, and formed ties with top suppliers at home and overseas to satisfy the firm's quality standards.

In the higher post he will still direct that division, work with product development to match engineering work to customer needs, and advance reliability along with fresh approaches. President Matt Fleming described Sheets as a talented engineer who tests what optics design can achieve and said the move will let him lead staff in creating high-performing products people want.
