I put together a 7 SAUM in late 2020. I didnt spec anything particularly hard to acquire; ARC action, PVA barrel and MagPul Pro chassis. Nothing arrived fast but it wasnt too bad a wait. The one thing that took the longest by far was the die set. And I even called Forster early on and ordered a set. MidwayUSA showed a set in stock from a manufacturer I'd never heard of but I held off. Eventually Forster came through. Hope you have better luck.
