Yup. I upgraded that exactly.
To a PVS-30. Not kidding. After shooting it for a while, happily, I accidentally looked through someone's PVS30, found they were still for sale, so I sold the Armasight, scraped together a few more bucks from spare gun-related things I sold, begged the wife for another $1500 and bought the better thing. Worth it.
But without the Armasight, I would never have gotten the clip-on bug, not known how good the better thing really is. I have done the same with my NODs, my thermals, and more. Good, functional items, then sometime new stuff arrives, a deal occurs, etc. and you spend a bit more to "trade in" and step up.
