How to make an ammo count "bar"?

So Im making a hud where I have a Red hp and blue armor bars. When you get hurt it goes down the amount you got hurt. How would I do this with ammo? I want whats in the gun and the extra bullets. Heres what I use for the armor

local Armor = LocalPlayer():Armor()
draw.RoundedBox(0,10,690,Armor * 3,30,Color(0,0,255))

How would I do this with ammo?
