Perhaps I'm once again being disentranced from this announcement, but I call bullshit. Not on the rifle, it's got to be top 2 ever invented.
But it's 100 years old. There is no patent on it. The parts were created 100 years ago, so they can't be that tough to make with today's technology.
I'm thinking if there were really a need for parts, there would be dozens of entrepreneuring gunsmiths out there looking for a military supply contract to supply parts to the Rangers. I can't believe there is no way to create a steady supply of parts, or an entirely new rifle based on the exact same specs as the original. I know from hunting that you can't take a any old rifle and go from horseback to rowboat to slogging through the muskeg to riding on a dogsled at 20 below - and just pull out the rifle and have the it fire when you need it to because you are about to become a bear snack.
My spider sense says there has already been a lobbyist who already has scooped up the contract, and the next gen rifle has already been decided. Stories like this are just biding time till the winner is announced.
I'm betting on the Remington 700. Wood stock, in standard NATO 7.62.
