What I would really like to know is how you managed to get that (AR!) spread on your screenshot. If I do the same (removing recoil and kickback, shooting from the same position right in front of the box), I get this. Left is the result from 3-shot bursts, right is an entire magazine fired in one go. Here is the result of 3-shot bursts with recoil.
What's in your screenshot looks more like SMG spread to me tbh, and that would be perfectly reasonable, given that the SMG is a close-range weapon.
