AMMO!
Problem: You havin a jolly time killin and you slap in a fresh mag and your out of ammo.
What you need: 3+ Mags, Electrical Tape, sand paper.
Instructions : First get in the habit of using your mags in a certain order (I go left to right from up to down). Take you last 3 Mags and place them on a table.
Grap you 3rd to last mag and put on ring of tape (about 3 layers thick) around the mag. Take the 2end to last clip and put 2 rings around the mag. Take the last mag and tape the sandpaper with the sand side out onto the mag.

So when you are reloading your fingers can keep count of you ammo count. When you touch two rings it is time to find out how you are gonna leave
