40mm/37mm Grenade Launcher Cleaning Tool

thingiverse

This cleaning tool is specifically designed for cleaning the bores of 40mm and 37mm grenade launchers, making it an essential accessory for any user. Two versions are included: a basic 40mm model and a more specialized 37mm variant. The 40mm version comes with two interchangeable tips - one fitting snugly into a 37mm bore and another tailored to fit even tighter in a 39mm bore. I personally favor the 37mm tip, which works exceptionally well for mopping purposes. The tool's design allows it to break down into three main components for easy storage, making it convenient for users who need to transport or store it frequently. Additionally, this design enables users to switch between different tips as needed. Here are the steps to use this cleaning tool effectively: To begin, insert the tip portion firmly into a microfiber towel or any other suitable cloth, holding the edge of the cloth tightly in place. Next, carefully trim the excess cloth material, leaving just enough to fold over and secure itself within the recess between the tip and the coupler. Once you've done this, tighten the coupler to lock the cloth firmly in position, ensuring a snug fit that prevents any further adjustments during use.
