I shoot a lot of 5.56mm out of several “Frankenguns” I have built out of miscellaneous parts.
One of the problems I have had to deal with is the practical packaging of “Ready Ammo”.
It turns out that regular, plain, old 2 ¾” 12 gauge boxes are the PERFECT size for holding 120 rounds of 5.56mm in stripper clips!!
….And once they are painted a nice, neutral color, …..It even looks like you know what you are doing!!
Just another suggestion from "The King Of The Cheap"!!!
