I have two registered, fully functional, MG34s. One is a DOT 45 and is civilian transferrable. The other is a DOT 44 and a dealer only "Post Sample". Both of my MG34s were manufactured by the Bruno Works in Czechoslovakia using tooling that came from Steyr. My DOT 44 MG34 is the one pictured below with my BREN. The BREN is also registered, fully functional, and civilian transferrable. It is a Canadian Inglis Mk II variety manufactured in 1944. Interestingly, both the MG34 and BREN were manufactured in the same year. Surprisingly, both are nearly identical as to length and weight.

Here is the MG34 by itself:
