Help a brother out to find and adopt a Sig MCX Spear 16 " in 308

As title says, looking for a new Sig MCX Spear 16" in 308 for a good deal. Looks like everywhere is out, not sure why?

I'm still kicking myself not buying one when I had the opportunity 😔. Max budget is $3500. Please help otherwise will get a used Scar17s locally with reciprocating CH for $2900 and spend the rest on optics 😕
