I to do not understand the crazy price but,
223 in this model is scarce.
Boat paddle guns have become collectable & are gaining steam.
Green stock inserts are highly sought after, if you're into that sort of thing.
New in the box for for a rifle that's a minimum of 22 yo.
A combo of all the above.
And,,,,,,,,,,,,, I still don't get it. But I'm not a collector.. This one might be the holy grail of the Zytels or something.
