This kit was designed to clean the gas tube without complete disassembly of the AR rifle. It contains two gas tube brushes and a clear guide tube.
This patented technology allows the gas tube to be cleaned easily and to save time without removing it. Simply insert the clear guide tube over the end of the gas tube. Apply a little of the Iosso Triple Action Oil to the brush and feed it through the gas tube. The combination of the gas tube brush and the Triple Action Oil will remove the built up carbon. A clean gas tube not only keeps your bolt cycling properly, but is helps prevent carbon build-up from being blown into the chamber. Complete instructions are enclosed in the package.
