Not saying it was the same for carbine stocks...but I went through 4 NOS scant field replacements, sending them all back with some sort of serious defect. They all came in original packaging, with gov. contract number printed on the side. First one had a mag cutoff recess that went all the way down to the bottom metal, second had a straight but way off-center inletting (obvious in the barrel channel and around the trigger), almost 1/4 inch off center. Correct width, but right side of the mag area was very thin. The third had almost 1/4inch extra gap behind the tang. All three came in their original packaging with the gov. contract number on the box, unstained. This discussion is starting to confirm my suspicion that the otherwise reliable retailer landed a pallet of factory seconds. The stained NOS scants at Numrich seem to be all Keystone. The inletting looks like it was scooped out by a spoon, but the fit is pretty spot on, with just enough room for minor finishing.
