As you can see below, the FG-42-II as well as its counterpart the FG-42-I (not listed) have a worse “Moving Dispersion Penalty” while in Hipfire (Higher means more dispersion = less accurate).
Hipfire is a useful tool in the game for avoiding AI fire, and in combination with some other stats, make the FG-42 less reliable in terms of accuracy. It is one of the only guns in the entire game to have a higher than 15 penalty here (except for things like Machine Guns).
This penalty also affects the accuracy of the weapon as you enter the sights, which can make it frustrating to miss when you are on target while aiming down the sight.
My suggestion is to equalize the weapons for parity, fairness, and balance.
