It’s no secret that the M2 stinger is perhaps the best machine gun in the game, and there are some changes that would both make it more balanced and more realistic.
The first change would be giving it a 100 round belt instead of a 200 round one. This would make it more on par with other machine guns, and make the weapon more realistic, as the 200 round belt boxes were determined to add too much weight to one side of the weapon, and were therefore never used. This would also make it easier for them to actually animate the belt, since I’m pretty sure the model has the 100 round box on it already and it currently just does a little jiggle to make the illusion of movement while not actually being animated.
The second change would be to add a usable front sight. The model in game has an M1919 sight modeled on it, but it is unusable as it is flipped down. Regardless, this isn’t even the actual sight that would have been used. In reality, the Stinger would have had one of these sights.
A change in sights would make the Stinger easier to aim with, more realistic, and would just make it look way better when aiming down sights.
