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.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.
