The name of the Chinese assault rifle barrel suggests that it is used with the Chinese assault rifle. It effects the base weapon stats, decreasing recoil and hip-fire accuracy while greatly increasing range and sighted accuracy.
The Chinese assault rifle barrel can only be found in the game files and cannot be accessed in-game. The mod does not have a crafting recipe, and loose versions of the mod do not exist.
