Why do we use a 36mm Main Tube? Only two words are required to answer that question: “Uncompromised Performance”
Our passion, dedication, and complete focus is building nothing but the highest quality rifle scopes. This is only accomplished with the most modern and technologically advanced optical and mechanical designs. At 37.9 ounces, the ZC527 is still one of the lightest weight rifle scopes in its class.
Our 36mm main tube allows us to deliver major performance gains both optically and mechanically. Historically, one of these systems is compromised in favor of the other. This compromise is non-existent in ZCO rifle scopes. Larger internal lens elements in critical positions yield the highest level of optical and mechanical performance in the industry. An incredible 35 mils of usable elevation and 20 mils of windage adjustment is available while maintaining consistent click value and reticle subtension.
The 36mm main tube allows additional internal room to isolate and protect the optical components to withstand external distortion, stress, and impacts. This results in the most stable and consistent optical and mechanical performance to maintain point of impact under a wide variety of environmental extremes. Our design is also stronger in critical junctions and mechanical areas due to a thicker cross section in specific areas.
The scope body is essentially an exoskeleton providing the foundation for the optical and mechanical components to come together, and ZCO goes to great lengths to build the strongest and most stable scope bodies in the industry. Every ZCO rifle scope body starts as a solid aluminum billet that is fully CNC machined and stress relieved multiple times throughout the machining process, virtually eliminating stress or “memory” in the scope body. Our machining process ensures your point of impact remains unchanged from moderate to extreme temperature fluctuations.
ZCO is a true specialty scope company building nothing but the finest rifle scopes with maximized specifications and the most modern feature set. We maintain an uncompromising dedication to superior design and are completely committed to ultimate precision, performance, and reliability. Every aspect of our products is analyzed, designed, and produced to meet this objective. The high quality and precision of ZCO rifle scopes will never be compromised nor sacrificed in favor of production volume. This philosophy is unwavering and paramount.
