Question about gun mods

how does each mod effect each weapon video proof would be appreciated and are some mods redundant in there effects like a accuracy increases for a dmr

There are some perks in weapons, i have seen
I unlocked 4 AR one with better range, better stability, more damage to vehicles and with silencer
And also a emp weapon with faster rate of fire and less overheat

I hope we start to see these type of guide videos soon.

ABSOLUTELY !! i hate when the game doesnt clearly explain key info!! …,what a strange way to try to add some kind of tactical depth to the game !!!
