Shanghai Changhong Optoelectric (China) rifle scope OEM

Shanghai Changhong Optoelectronics is a rifle scope OEM in China. From their name, it appears they are owned by Changhong Electric, a major Chinese electronics company, and the leading producer of TVs in China. Shanghai Changhong OEMs rifle scopes, prism scopes, and reflex red dot sights for Hawke, Sightmark, Riton, TruGlo, and Vortex (Diamondback Tactical rifle scopes). They also appear to be the owners of Swampfox Optics.

Disclaimer about OEM information

It is difficult to talk about where "optics are made" because they are complex instruments, often with various components coming from different suppliers. For example, raw glass comes from a handful foundries worldwide. Raw glass blanks must be ground into lenses and coatings applied. Then these lens elements must be assembled into optical subsystems (e.g., objective lens assemblies or eye piece lens assemblies). These steps may be performed by a single company or by a series of companies before being sent for assembly into a finished optic. Even when performed by a single company, these steps may occur in different facilities in multiple countries. A similar series of steps are associated with machined parts like main tubes and turret housings, finishes, etchings, small parts, electronics, reticles, etc. This inherent complexity is why I focus on where the final assembly takes place, as this question has a more definitive answer (although even final assembly can be murky).

OEM information provided here should not be taken with 100% authority. I rely on import/export data (e.g., SKUs in shipping manifests), brand websites, published articles, and forum posts by reputable industry insiders. In a few cases, I make inferences from product similarities or by process of elimination. I provide OEM information, when available, to provide insight into the optic industry supply chain.

Shanghai Changhong appears to ship under both their own name and via a separate export company named Cape Evolution.
