Re query are plans semi auto.
(I have recently acquired a full set of drawings (not scaled) for the Australian F1 SMG 9mm sadly killed off because someone invented the AR 15 lighter & with a better cartridge.
What makes it interesting is it used a single bar sear (same as M60) 2 stage trigger pull semi to full auto meaning no selector. When I get time I will use my limited abilities to get working drawings posted of the mechanism.
As far as I can tell they are full auto. They are original drawings.
I did spend a lot of time carrying the M60
I doubt the receiver has anything to do with making it semi auto.
The trigger was full auto only unless you were quick manipulating it. One of my favorite tricks was to count from 1 to 10 rapidly (Single shot, Double, Triple, Quad etc up to 10 in bursts) the feed cover & plate are continuous feed simply pulling the next round across.
Unless you can find someone who has built one semi auto it would require a special trigger sear setup to disconnect after each trigger pull. That is as much as I can help with.
