I recently purchased an M&P MOE M4 that apparently is an 'Airborne Edition' with the Airborne logo emblazoned on the right side of the receiver, and a 'Helicopter Gunner' logo etched in to the left of it. I got it from the original owner (an Afghanistan war vet) who stated that it is one of 200 made, and is currently unfired. However, I can find no evidence of any rifle like this being produced by S&W, and no one seems to have any knowledge about it. Since I only paid $250 for it ( yes, I ran the numbers...it's clean) because the guy needed the cash, I'm not too worried about the value. But...what exactly do I have here?
