RUSS LEONE

"This is not what we do, it is how we live".

Co-Founder and CEO

Russ Leone is a co-founder and the Chief Executive Officer of Leone Development, LLC. He has a successful track record in manufacturing, general management and technical servicing with a Fortune 250 company in the forest products industry, and privately owned operations in the printing industry. 

Russ’s career responsibilities were focused on process improvement and product development where he drove the logistics and customer requirements for the launch of new products and the oversight of product performance at world-class paper manufacturing facilities producing in excess of 1M tons of paper and $1.5B of annual revenue. 

Prior to his tenure in paper manufacturing, Russ managed operations in the largest printing facility in one of the largest markets in the US, overseeing the production and delivery of $20M+ of annual output. 

He has developed particular strengths in customer relationships, managing people for productivity improvement, equipment problem-solving and training—he developed and taught a printing course at Lower Columbia College in Longview, WA. 

In Tandem with his career in printing and forest products, Russ has also operated privately-held companies in the firearms industry, which led him to obtain his federal firearms license in 1980. 

His mechanical acumen and career engineering experience, coupled with his deep understanding of the technical aspects of firearms (acquired over decades) have led to the design, prototyping, patenting and production of the LEONE Barrel which was patented in May of 2018.
