A fellow asked me to look at a Garand he just inherited. Mid WW2 serial number. It has an 03A3 2 groove barrel on it. This is the second one of those I have seen. The original barrel stub was bored and threaded, then the A3 barrel was turned and threaded and screwed into the stub. It was certainly very labor intensive and it is a quality job, not a BUBBA project. The first indication of the job was the barrel was blued and the rest had slight pitting and was parkerized. It appeared to function quite well and I think it would be good shooter.
