40mm/37mm Grenade Launcher Cleaning Tool

thingiverse

This is a cleaning tool designed to clean the bore of 40mm and 37mm grenade launchers. Included are two basic versions: 40mm and 37mm. The 40mm includes two different tips, a 37mm and a tighter fit 39mm. I typically use the 37mm which works good for mops. The tool breaks down into three basic pieces for storage, and also allows for different tips to be used. <b>How to use:</b> tightly push the tip portion into a microfiber towel or other cloth holding the edge firmly. Trim the cloth leaving a small amount extending past the edge of the tip. This extra material will fold into the recess between the tip and the coupler. Tighten the coupler to lock the cloth in position.
