Uses M3 bolt that you “turn on a lathe” (or just use your drill and a file) for centering in the gas port. Use an m3 drill for the dimple at least to start, or whatever else you want that fits.
Print solid plastic, figure one time use. For my Aero barrel, the fit is absolutely perfect, but you may need to play with scaling to get it just right on yours.
Enjoy.
