I had the opportunity to compete in a German Air Force marksmanship event. We shot the HK G3 in 7.62x51 NATO,Walther P1 9MM, and the MG3 in 7.62x51 NATO. We discussed the MG3's heritage the MG42. The MG3 cycles extremely fast; I could"slip trigger" it but the fewest rounds I could fire in one burst was three. I could get our M60 machine gun to fire single shot by being very careful. The Air Force soldaten told us they had two springs for the MG3 and it was issued with the weaker spring.
