I recently purchased a M1 carbine barrel chambered in 5.7 Johnson. It is a shame this carbine was parted out. The seller said it was USGI receiver and parts. The barrel is blued and the only mark is a number 6. (or maybe a 9) I would like to have a carbine re-barreled with it and understand there are some concerns I should be aware of. I have been interested since I was a kid in the late 60's when I saw a carbine in 5.7 Johnson pictured in a Williams Gun Sight catalog. The catalog also featured William's "1 of 50" M1 Carbines and almost fifty years later I was able to purchase one of those. So now it is time for a 5.7 Johnson carbine.
Any help is appreciated,
Rich
