Still some question as to whether or not the import is really going to happen. I believe the part about no carbines though. Those are some serious gang-banger, cop killer, drive by machine guns!! (can't find the "puke" smiley)
I think the $220 quoted was what somebody thinks is the going price for carbines. Not hardly. More like $5-600 for starters.
Who knows what the Garands will go for if and when it happens.
The CMP (Civilian Marksmanship Program) is still a great place to get a Garand. You're guaranteed a safe, functioning rifle. Their armorers are THE experts on Garands and go through every rifle before it's sold. They start at $600 for a rack grade. They don't have carbines any more, other than some high dollar auction stuff. I jumped on one for $500 2 years ago when they had some for sale for the first time in literally decades. http://www.odcmp.com/Sales/rifles.htm
If you can find a carbine their great little handy rifles. Light, short, easy to shoot. About the same ballistics as a .357 mag. Not tackdrivers by any means but decent 'battlefield accuracy'.
All that said, and I love and shoot the Garands and Carbines, I don't know how appropriate they are for prepping. Garand is big and heavy, only holds eight rounds and shoots a big expensive 30-06 round. Oh, and don't use just any commercial load. A lot of modern stuff is too hot for the Garand's action.
Carbines are great, but not real cheap, not as common as they used to be, and the ammo can be downright hard to come by. And pricey.
