it is one thing to "correct" a carbine with no barrel band shadow or adj sight stake marks for your own pleasue but when they stand out like they do on this carbine it would be a distraction of sorts. Best to keep the adj sight, barrel band w/bayo lug on it. It is part of the carbine's history, nothing wrong with that. Lots of M1A1icon carbines went through the rebuild process (RIA stamp) and were upgraded to those parts so having it with those parts in that stock will still be "correct" for it.
