Are you talking about Larry referring to the M203 in the video? He was in service starting in the 80s. Anyhow, I wasn't trying to prove any point by it, just supplementing Parzival's discussion on the topic.
I don't see it that way but ok. I just get the whole vibe of pre-MW CoD which I hated in the step back from the gunsmith-centric design, gameplay, reintroduction if Zombies, etc.
MW was a departure from some of that which got me back into the game after many years. ....but that's just me.
