The backstory: My son (15 yo) is an avid WWII amateur historian and has been seriously hankering for a Garand for some time. Well over a year, which is a long time for a kid. We're going to Port Clinton for a walleye charter in July and our motel is a mere 15 minutes from the CMP store. He's got a bout $600 saved up l'm willing to chip in more to get him a nice rifle. Which brings me to the question: They are showing service grade for $750 and "CMP Special" complete refurbished for &1050. Is there a reason to avoid the refurbished rifle? I want him to have something that will last and be serviceable his whole life.
