(adsbygoogle = window.adsbygoogle || []).push({}); To get 5 m203 grenades for one gun (and 1 for the other gun) have the overkill perk and put grenade launchers on both guns. Now you have 5 grenades for one of your guns and one for the other. Sorry no video.

overtubing only gives u 3 for 1 gun and 1 for the other. 2+2=4, not 5.
