Just a suggestion, when selling bare/not assembled recievers to customers, place a mark somewhere on it as a record of how it left your shop. Manufacturers of different firearms in the past who started selling bare recievers had people later confuse home builders messes with in house manufacturing and it hurt their reputations as a builder. Make sure either different serial number font or a specific mark that down the road if someone creates an abomination of a build you can say, "see that?, that was a homebuild" (and more importantly people in the know would be able to say, "no, see that there, thats not a Dakota build"
Edit: maybe a prefix on the serial number like BR for bare reciever, and BT bare with trunnion.
