It appears to be a blatant rip off of the Otis BONE at a 30% surcharge. I talked with the owner of Otis years ago, he was at the annual sniper comp on Bragg giving out swag and breaking down his cleaning devices. Dude is a wealth of knowledge, and not in a snake oil salesman way. His tool is designed to remove excess cardon, not physically drag on the walls of the metal itself. So it won't "G.I." clean the BCG but just remove elements that cause friction - someone like me who shoots a couple hundred rounds suppressed and then leds my gun sit for 3 months in it own filth, really appreciates that.

Not to carry on about my man crush, but Otis's variant of a bore snake. the Ripcord, is revolutionary. Yea it is pricey, but when you use a cheap bore snake and drag it through your barrel, it strecthes, therefore only the front and end of the bore snake actually contact the rifling, where as Otis "ripcord" is designed to not hourglass shape when being pulled through the barrel. This is the same guy that was telling people to dump their steel cleaning rods (for anything except expedient case removal) a decade before it became common knowledge
