What the columns mean for this weapon

How to read it

Pen is the round's penetration figure; Class is the armour class the chart rates it to defeat. Against a plate one class higher than the round, expect most hits to be absorbed. The strongest 5.56 here is rated to class 5; see every round that beats class 5.

Flesh is damage to an unarmoured hitbox. High-pen rounds usually trade flesh damage away, which is why the two picks above are rarely the same round.

The weapon itself does not change these numbers — its fire rate, recoil and effective range decide how many of them land. Those are on the SG550 page; compare it with other assault rifles on the Assault Rifles index.
