Anyone know where I might find a 18.5" barrel for a mossberg 930?

Specifically, this one: https://www.mossberg.com/store/930-12-g ... 93020.html

I've been looking for months, everyone is always out of stock. Anyone who lists the SKU says "backorder, overdue". Mossberg says no inventory, and no ETA.

It also seems that nobody has had new mossberg 930's in stock for as long. Kind of feels like mossberg has stopped manufacturing the 930?

I'm guessing it is simply a case of demand exceeding supply, all HD guns and ammo are very scarce due to current chaos.
