Re: Choosing a garand
Well, other than examining the action, looking down the barrel (some will have really dark bores), and doing the "bullet test" (get a standard FMJ ball 30-06 surplus round and stick it in the muzzle, pointy end first - if it goes all the way in to the brass then you know the barrel has some wear, at least at the muzzle end).
Be prepared for common problems like the ejector spring, lots of them are old so instead of the *ping* as the stripper clip is ejected, you get a *bonk* because it pops about 1-2 feet into the air and lands on your head.
Also, (if prices around here in cali are any indication) expect to pay 500-600 for a basic plinker and 7-800 for one that is nice and clean with a good barrel.
Joining the CMP and buying one from them, or getting a CMP member to get one for you is the best way to go.
