Yes, and here are my thoughts:
Remember that "NRA-Good" condition does not mean what most would consider "Good" condition. "Good" means that, basically, the gun is all there, not broken, and has something of a finish left on it.
In making sure it is safe, I would check the bolt serial numbers and the receiver serial numbers. The two, ideally, should match. However, on many guns they don't. This is okay, but just make sure the headspace is good. Have the dealer (or, if you can, do this yourself) headspace the gun with a No-Go or Field gauge. If the bolt closes on either one of those gauges (make sure the chamber is free of muck and that the extractor is removed prior to inserting the gauge), pass it up. It may not be safe to shoot.
Basically, I would pass up "Good" condition guns and look for "Very Good" condition weapons. However, every gun must be evaluated on a case by case basis.
