Lee Six and Chet Brown made the first fiberglass stocks.

At one time Lee Six made stocks for Remington back in the 80's and he helped Mel Forbes set up his stock making for his light rifles. I'm guessing stock may of been made by High TecK Specialties it's company that Mark Bansner purchased in the 90's and you could custom color them and Metallic was big back then. I send mine out to hot rod paint shop and good paint job cost more than paid for stock.
