Tucked just beyond the front range of the Colorado Rockies, you’ll find a factory where some of the world’s best premium hunting optics are built. Here’s an inside look at the operation that supports Burris and Steiner.


burris-tour2Today’s factory tour occurred while Steiner riflescopes were in production. My first impression setting foot on the factory floor could be summed up like this: remarkable cleanliness and organization combined with machine technology and skilled craftsmen/women, with purposeful focus on build quality in a safe manufacturing environment.

burris-3456High-quality single-tube riflescopes such as those from Burris and Steiner begin with high-grade aluminum blanks. Blanks are stacked and ready to be turned by expensive CNC machines with incredible precision. The bits shown here (far right) are used according to the specifications of the wide variety of scope tubes created. Aluminum filings are the by-product of the process, which are recycled. The freshly minted tubes shown have a 56mm objective and are for the next phase of becoming a fully functional riflescope.

Notice the far wall with small windows—technicians seated at each window test every scope to make certain both optics and reticles meet rigorous standards at distant targets from the building.

burris-eliminatorThe popular Burris Eliminator laserscope is being tested for a variety of optical quality standards before getting boxed up for customer shipment. The technician gave me the opportunity to get behind the scope to walk me through the checklist of what she was testing; it was impressive!

There was a huge room with benches and testing equipment to help customers around the globe get their scopes back to working order. An adjacent room had scope and binocular parts organized in rows of cabinets and labeled storage bins. Decades-old scope models are brought back to life, as well as new scopes that endured a mishap on a hunting trip or military exercise.

I’ve never taken a complete tour of an optics facility, so I have no basis for comparison. However, I was truly astonished by the care, precision, and professionalism on the Burris-Steiner factory visit. Maybe there’s a reason they offer a Forever Warranty
