I made mine. But whats wrong with the Gibbs "A4s. I've heard people complain about them, but then the people I seen shoot them in the CMP Vintage Sniper Matches swear by them. They do quite well, only thing that beats them constantly is the A1 with the 6X scopes.
I guess it depends if you want a "collector" or a shooter. I wanted a shooter, at my age I have no use for collectors, I'll be long gone before they rise in price to make any money, but I'm young enough to shoot the vintage sniper matches.
Like I said, I built mine, Someone gave me the action and most of the parts. I had to buy a barrel and stock, but its all GI except for the repo M73 scope.
Real A4s were Remingtons, mine is a SC, but still legal in the CMP Vintage Sniper Rifles.
