I have an original Remington 1903 made in late 41. All original and correct parts. No rebuild and very little wear. A Beautiful rifle. For some reason it has a biscuit cut on the upper hand guard even though there is no sign of any damage to it. It is the only flaw on the rifle. Is this commonly seen on the ANZAC guns? Could it be a precaution to possible damage? I see biscuit cutts on many British Enfields but never on 03s. I was thinking of replacing the hand guard but havent found one with the exact same length of sight groove. Or should I just leave it alone? Thanks in advance.
