    The second you slot your open bolt to clear the blocking bar, the bolt (by its self ) would be considered a machine gun ..... and if you manufacture an Uzi receiver without the bar, it's a machine gun....

    As far as the M11A1 goes, the fact it's made on a flat that was manufactured after RPB went out of business pretty much guarantees that it's post-82.

    I honestly never remember seeing a MAC flat for sale prior to 1982....... ever

    I found this video which I think is the video RPB made for the court case in 1982

    Maybe carbon dating but I'm no metallurgist and only have a basic understanding of what happens to metals and their structures when heated, melted and formed.

    This is the answer. The logo was changed when SWD started to a circle around the cobray and the word cobray beneath. That makes this contraption post the June 21st, 1982 cutoff of open bolt semis and after RPB had ceased to exist.

    playing devil’s advocate - in a criminal trial where the standard of proof is “beyond reasonable doubt” a defence could be this open bolt gun was made prior to June 1982, by someone who made their own receiver flat before ”receiver flats” were even heard of, and then, at a later date after June 1982, the Cobray logo was stamped onto the lower to give it a more authentic look.

    Aside from laser engraving that is available now, I personally remember seeing for sale on the old sksparts.con site (remember them?) In the early 2000’s at least one Cobray punch stamp for sale.
