Well, thanks for answering my question. I find it stupid to charge that much for a clip on, that makes zero sense.
I hear ya and I've thought the same thing but honestly it makes sense when you really lay it out.
You take all the same guts of a thermal scope, make it as light as possible, design it in a more compact modular housing that can be attached to almost any rifle scope on the market and do so without scratching or damaging the bell of the scope. Then you make an eyepiece that can be quickly attached to turn the unit into a monocular and you've now spent a lot of money. Then know that you are going to sell a tiny fraction of units compared to weapons mountable optics. It's necessarily going to cost a lot more money for the company to produce. Trust me if Pulsar could sell them for $2,000, they would.
They've had them sitting on the shelf in inventory with no one buying them for the last 6 months while everyone is begging for thermal scopes.
Think about it.....they are so unpopular almost no one is making them and the Trijicon version is $10,000 and you can buy the REAP IR which is basically the same unit for $8,000.
The truth is, if the clip-ons cost the same as a regular scope I'd still advise against them. They will just never be as good as a dedicated thermal scope but again, for some people, they are willing to make sacrifices for the convenience and I understand that.
