This is a new Fusion Barrel Bushing for commander sized pistols and clones. This barrel bushing has been produced to be "drop-in" style. It was made a bit larger at the critical contact points to make a tight fit with the slide and barrel. All machined in the USA on state of the art CNC turning centers. All machined from pre-hardened bar-stock. Absolutely no warping or distortion from after machining heat-treat processes. All made in the USA.
