I am not sure which one would freak me out more, go against an M2 50cal, or MG42. Just wondering. Which one is quicker to reload and the M2 had changeable barrels?
M2 had a changable barrel, but it was not a fast process, you undid the hot barrel, screwed in the fresh one and then set the headspace and began firing.
that said, you could simply push a new belt in the side of the feed area and #### it twice and fire to reload, the mg42 had to open the top cover and position your belt, then close and #### before firing
