I've owned both a preban 20" and postban 16" Vmatch, and have since sold them years ago. They came out in the mid 90's and were available only with the Hbar profile, and are in fact heavy to hold. The metal tube is cold to the touch in rain or winter, and gets very hot to hold as soon as the first or second magazine is fired (even on slow firing). The tube has no ventilation holes whatsoever, which not only dissipated the heat poorly, but caused a lot of smoke to exit out the front and blur vision on the sights (scope or irons). The tube had no rails, nor provisions for a bipod or even a sling mount. Bushy left the barrel sling loop installed, which when used negates any accuracy benefits of a FF barrel.
In summary, you basically have an upper designed about a decade ago which is far outdated when compared to what is available now. Although it will shoot fine, the previous owner probably felt the same way and that's my guess why it was sold.
