If the FG-42 was such a great gun, then why didn’t it get used after the war? Well, two answers…
1) It was crazy expensive to make and there weren’t very many lying around for people to use in quantity after the war.
2) It was used; there was at least three post-war development projects based directly on the FG-42. One was the British EM1 Korsac Light Automatic Gun, one was the Swiss WF Bern competitor to the SIG Stgw 57, and one was the American M60 GPMG. So let’s have a look at all three, and what they did or didn’t take from the FG!
