I agree that except for the rimfire panic days, no one was paying those prices for 22 LR
$40 for an Anderson lower is for a stripped lower. He said it was a "complete lower:, which I took to mean it had the parts kit installed and possibly more. The Anderson website lists a "complete lower" at $211, for instance....
I don't know what sort of overhead the dealers you mention have, so I wont comment on their pricing decisions.
Sorry, I meant a non-80%. Not complete. My bad.
