Polymer coated ammo and bore fouling

Well I definitely want that, so point taken.

The only time you want to 'scrub' a barrel, is when your gun can no longer hold a(known) group.

I would push a lightly oiled patch through the bore, only if it had a lot of particulate matter in there, and only once. We hunters(and other shooters), like to keep a "dirty" bore where we left it.
Shooting a scrubbed clean bore is almost like pulling a brand new rifle out of the box and expecting it to hit dead center.

You should always keep a fouled barrel on any gun you want be able to pick up and hit with.

Yep. I almost never clean my ARs. Maybe a wipe down and some oil.
