Bring back the old HK416 and R870 models

The new models are nice, sure, but they don’t fit the overall Pathos art style. They feel out of place compared to other gun models.

I think going back to the old models would be better, and just add a little quality of life when using these two guns.

As for the HK416[S] model, I’m sure adding the suppressor to the barrel wouldn’t be all THAT hard in regards to a revert.
