Rifle has a rotary 10-round magazine, looks pregnant or something but it works fine.
MG used 20-round single-column curved stick mags.
Fair bit of parts commonalty between rifle and MG. Under field conditions, you could keep an MG running with spares from rifles.
Brilliant design, really.
Fritz ripped of the trigger mech for the FG-42: semi on closed bolt, FA on open bolt.
ALSO: it can be made in just about any decent machine-shop AND it is extremely tolerant as to ammunition performance and headspace issues. In the tests at Springfield they mixed 100 rounds of ammo, everything from Proof rounds mixed in with seriously-underpowered stuff. Rifle ran perfectly, didn't care what it was eating as long as it got fed.
The multi-lug Johnson bolt is with us today in miniature form; look at an M-16. Johnson did it better, though.
