Follow-up video featuring RPO 3.0 can be found here: Read the full write-up here: This is a full video showing the differences between US Milspec (Carson) vs RPO PVS-14 lenses. One isn't necessarily better than the other as each individual's requirements and priorities will differ. RPOs shave at least 74g off a binocular night vision system but at the expense of some optical trade-offs like rainbow flaring and chromatic aberrations.
