The expression "necessity is the mother of invention" must have had Dave from Calbico in mind. Frustrated with the nooks and crevices of various firearms and attempts to get crud removed from same, Dave finally broke down and did the unthinkable: He made his own cleaning tool.
The Calbico Channel Cleaning Tool is one of those things that, when you first look at it, you kind of scratch your head and wonder what it is. Did it escape from a dentist's office, perhaps? Is it some sort of space-age micro-pry bar? And then you sit down with a filthy semi-automatic handgun, and you realize that the channel cleaning tool allows you to precisely wedge a solvent-soaked patch exactly where it needs to go to get things cleaned, and I swear you can hear an angelic choir in the background. Okay, maybe that's overdoing it a little, but this tool is one handy little piece of kit.
It has two different sides of different thickness. Between the two, and whether the tool is held horizontally, vertically or somewhere in between, you should be able to reach the overwhelming portion of your dirty gun. Tried to clean the gunk out of the AR-15 breech? The Channel Cleaning tool can help. Shot a bunch of really dirty ammo in your Glock and need to clean the slide and frame thoroughly? See the last statement. The Channel Cleaning Tool is more precise than a Q-tip, more useful than a toothpick and doesn't spray solvent everywhere like a toothbrush.
