I agree that there's somewhat gap between K43 and garand.
If anyone noticed or not, I have been playing on allies side quite often testing out the guns. The K43 seems to be really losing the ground against the garand due to the fact that the damage coming out from garand is pretty much either 100 or 120 damage. I rarely saw it doing 90 damage where K43 did it most of the time.
I think the gap is not much noticeable until it goes to the hands of skilled players.
