I notice that each gun has stat for power. What does this represent?
If you look at the stats for a gun on the wiki, you'll see that base damage and power are listed separately. Also, on the wiki page there is no statistic for a gun's target knockback. However, in the Level Editor, we have a trigger action for modifying a gun's target knockback, but no trigger action for modding a gun's damage.
So this has me confused on what a gun's power is supposed to affect. For now I am assuming that it influences the damage a gun deals, although I think it might be possible that power is a combination of the gun's base damage and target knockback.
