Don't you love how Airsoft companies misidentify guns? ;)

Not only were M14s not available during WWII, but it is, as you said, an SKS (which was also not available during WWII to my knowledge). I saw a Micro Uzi labeled as a Mac-11 somewhere too. The name doesn't matter though, people like buying guns or things that look like guns.
