I have a preban Colt 9mm lower that was remarked to SMG (Sub Machine Gun). The selector is marked SAFE SEMI AUTO. The lower has M16 parts, ready for your RDIAS. $1250 shipped to your ffl. ***ALL NFA RULES APPLY***
I will remove m16 parts and ship seperate from lower to comply with BATF rules. If you do not have a rdias you need to replace these with semi parts.
