in this instructible, i will show you how to make an airsoft ammo holder out of a pen tube and a pill bottle.

Step 1: Materials

Picture of materials
1)9/32" drill bit
1)bic pen&pen cap
1)pill bottle
I usually use pill bottles just to carry airsoft bb's around with me in a war. I have a huge old motrin prescription bottle that holds ~1000 bb's, which I use to fill my hi-cap mags between engagements.

Good 'ible, however I would suggest drilling the hole on a farther side and having the magazine(or just the bottle) at an angle s the bb's can feed into it easier.
lol, the last pic looks like the spray paint thingy, only it sprays BB's!!!
it's semi auto, it doesn't technically spray BBs
until you blow into the hole...
lol, *voice turns into some weird epic narrator voice* until you blow into.... THE HOLE!!!!! I can see this as your latest project both from personal interrogatives and your psychological profile (which I know little about (psychology)).
