Sounds like a pretty good example - you might check the barrel numbers yourself, as the CMP hang tag numbers sometimes are pessimistic. They use gauges that get worn down from constant insertion, so the numbers can be a bit high. Too bad the stock doesn't have IHC markings, as that item alone is the most expensive to correct aside of the barreled receiver. I assume you did check the barrel channel of the stock for an alphanumeric code? At least you got an IHC op rod and bolt, and the trigger group is easily corrected if you want to go that route. Can you post pics of the rifle, please?
..Yah very true on the tag numbers versus checking yourself.....My IHC I bought from CMP earlier this year had a tag measurement of 2/3 it turned out more like 1/2 using the same tools as CMP......My field grade with LMR barrel was all matching IHC except stock and safety...Luckily I had an IHC safety in one of my other CMP rifles so I traded them out, but sure wish I could find an IHC stock to buy!.....I had heard the field grades had more matching parts then the service grades...anyway congrats guys!
