Damn, Jmr40 rings in solid again!I wouldn't trade an AR for a Garand unless I had another AR. Not right now. It will probably be easier to find another good Garand than AR in todays gun climate.
I have a total of 4 AR's in the house and if someone offered me significantly more than I paid for it right now I might consider trading one to buy a Garand. But if it were the only AR I owned I'd be keeping it. If you can afford to buy the Garand without letting the AR go, or by selling something else then go for it.
