Like finding a unicorn,
A few years ago I bought a .54 Thompson center Hawken with a corroded barrel, it was a wall hanger on the same wall since the mid 80's the previous owners fired it a few times with pryodex then hung it up without cleaning.
I bought it for $150 other than the barrel it's in pristine condition I thought the parts were worth at least that, found out later Green mountain stopped making replacement barrels in 2009
A buddy told me he saw some Green mountain barrels at a gunsmith's shop in the basement I emailed the guy sure enough he had a drop in barrel unit, a Renegade 54 1" on the flats same as the Hawken I would have preferred a 1:66 but pickers can't be choosers
nothing like finding new old stock in the box
