I still don't understand what the big problem is, even though I've been brought up to speed by those in the know. It's a free market - pay those prices if you want.
Fulton has earned a bad reputation in the competitive shooting niche... such that, some members here on THR wouldn't even answer a question I posted about Fulton... they have boycotted all Fulton Armory threads! "They" aren't reading this thread, either, probably.
Anyhow, I just got an M1A NM Hooded rear sight (complete) for $100 from a private party... same part goes for $150 plus S&H on the Fulton Armory site.
It DID take me a few weeks of hard searching (and the right friend) to find this part cheaper, but ... I like to hunt, and I like my $50.

..oh yeah, and I HATE pop-up ads on websites, and Fulton is guilty of this. Thanks to Mozilla, it's not a problem any longer.
