I picked this M1 Carbine up last weekend: The previous owner thought the barrel was a refurb because it was a Marlin barrel but believed the rest of the rifle was all-original NPM. It was priced accordingly for a refurb, so I went through with the deal and did some research when I got home. I was pleasantly surprised to find that National Postal Meter did not manufacture their own barrels, and that a Marlin stamp with no date does indicate an original barrel. Lucky me, judging from what like weapons sell for on gun broker this gun is possibly worth twice what I paid for it. Which leads me to my question for you good folks. My goal has been to collect low-budget milsurp rifles that have historical significance but which are NOT too valuable to shoot. That's why I was looking for a WW2 era refurbished M1. I'm going to keep the gun regardless, but in your opinion is this gun too much of a collector's item to shoot?
