Yes there are 86K rifles loaded to the PI that will be returned to the army, then the CMP. BUT they will all have to be gone over by their armors, to check, repair, or strip for parts depending on the rifle.
The CMP had several thousand MIs on hand now, but are backlogged in getting them ready for sales. Right now they are trying to fill the back log from the last Field Grade offers.
One just has to be patent. Keep an eye on their website (sales), When they get caught up they will make another offer, And like before they'll be flooded with orders. Then they'll shut down again until they get caught up.
They have M1s now, without the PI rifles, so I wouldn't wait ,soon as they list them, jump on the band wagon. I have two, and just bought a third for my son. Shortly after I got my order in, they stopped taking orders, but the orders were on hand were filled.
The one I just got was a Field Grade but it was in excellent shape, and shot well.
But again, keep track of their web site, more will be offered before they are close to be ready to sell the PI returns/
