I know i'm very late, but i'd like to point out that the 2023 stamp on the gun doesn't necessarily mean it was invented in 2023, just that particular gun was made in 2023.

Also it's unreasonable to expect 4a to change the weapon models just for a dlc, which is why every lolife you find is stamped with 2023.
