First off, welcome to the FTF community. When you get a chance, head over to the new member thread and introduce yourself to the gang.
About all I know about CAI Garands is that they have a cast receiver. Personally, I don't care for the idea of a cast receiver. Just my preference.
You can get a real
G.I. Garand from CMP for just a bit more money.
I have a '43 Springfield Garand that came from CMP and it's an outstanding rifle. If you can, buy the real deal. You won't regret it.
