I know this has been answered before but my brain is blurred from working on my first NFA eForm 1. I executed my NFA trust today and began completion of the Eform. I want to get my lower engraved ASAP but was curious about the ST. abbreviation for SAINT (LOUIS). I have seen examples of Missouri SBR engraving where ST. LOUIS, MO or ST. PETERS, MO have been used but I've read other places that only the standard 2-letter State abbreviations are acceptable. While I know by the examples that others have used ST. instead of SAINT, are these acceptable by ATF?
While I am making this inquiry, I remember reading about someone in the Silex area who does nice SBR engraving work. I want to get mine done on the front of the mag well. It would be about an hour drive each direction for the Silex area so I hope this is a "while you wait" possibility. I haven't heard of any nice quality STL engravers but would be open to any suggestions.
Thanks!
