I will build my own M1 Carbine in the following months (money need to flow...as I am also rebuilding my house). I have a barrel I bought on Gunbroker last year https://www.milsurps.com/images/imported/deleted.gif
I know that it is an odd shaped barrel but for the price....it will be a good shooter on the pistol range ! I am planning to put it in an Underwood receiver and a M1A1 stock. Let's the fun begin !
