Southern California Stock will be playing an Ammo Box only game at Jungle Island Paintball tomorrow in Lake Elsinore so I've gathered a few of my favorite options for Ammo Box loaders.
My number 1 pick for uniqueness is the Ammo Box 2. Fearless Leader didn't mention that Ammo Box 2s aren't allowed since he probably figured most have shattered because of the brittle plastic they were made out of. The Ammo Box 2 pictured above is the exception. It's made from a softer and more flexible plastic that actually allows it to withstand direct hits! This loader also features a platform inside which I'll have to remove before it can be used (reliable). The pictured side piece on the mid right side of the photo above holds your barrel plug.
And above is a PMI Ammo Box with a PMI branded Butler creek scope lid flip top.
