The mod replaces the old GTA 4 scope with the new one that was in the GTA 5 gameplay video. A little about the crosshair: If you aim at any ped, the crosshair will be just a white dot. If you aim at a cop or an enemy, the sight will turn into a red cross, as it was in the video. If you shoot, the cross will disappear.
I'll review the gameplay again and maybe I'll torture it even more)))
Installation: Drop the pc folder that is in the archive into the game folder and confirm the replacement.
