These clamshell tools are precision waterjet cut out of HDPE for a precise and tight fit that conforms to the lines of our of compensators, preventing damage to the finish of the compensator.
Simply press in your PMM comp, tighten the tool down into your bench vise, and begin the installation process.
To help aid with finding the proper pretension of the compensator before applying threadlocker, our “Muschi” line of clamshell tools include a front sight post cutout. When the proper pretension is found, you will be able to see the front sight post through the cutout.
