You know that it is darn near impossible to properly clean the M1 Garand chamber. Over two years ago we came up with a simple and inexpensive way to keep that all important area clean, the m1 Garand chamber cleaning tool. We have now improved it by giving you the option to quickly remove the cleaning patch jag and install a chamber cleaning brush that we have included in the package. The rugged poly Universal joint allows you the ability to easily get into the proper area for thorough chamber cleaning. All parts that come in contact with the chamber are manufactured from non-marring material.
