This pivot screw fits the 3.5″ XM-18, 4″ XM-18, 3.5″ Eklipse, the 3.25″ MP-1 and the 2.75″ Half Track.
Please use great care when installing the anodized Ti pivot screws, if your screw driver slips it will more than likely scratch the anodized finish. The Hinderer Armorer’s Tool has a precise fit screw driver blade to help eliminate any movement inside the slot that can damage the finish. If using a standard screw driver, we suggest putting masking tape on the tip to prevent marring of the finish. If you do damage the finish inside the slot you can use 360-600 grit sandpaper to sand the slot uniformly for a 2-tone finish. We are not responsible for any finish scratches during installation.
