Unlike their previous model that literally shows a rotary countdown wheel with the number of rounds, their new Three Window Mag takes that idea and makes it a bit simpler. Instead of having to squint in the heat of battle at a little number at the lower end of the mag, the TWM gives a sort of "Green, Yellow, Red" indicator of your ammo capacity.
