Thanks all. There is no need to engrave anything as my Form 1 clearly states that FNH Belgium is the manufacturer which is alrady engraved on the weapon.

The serial number must be engraved or stamped on the receiver of the firearm and the caliber, model,
and identification of the maker must be engraved on the barrel or frame or receiver of the weapon.96 The
marking and identification requirements for a maker are the same as for a manufacturer.

FNH did not make it an nfa firearm, you did so your info needs to be engraved on it.
