Black option has a thin coat of paint.
Gray option is unfinished and is best if you are planning on a custom paint theme.
This product comes with 2 small screws that are inserted into the bottom of the hand guard, these screws are more for the details of the design than they are for clamping force. However, they will help clamp the hand guard down slightly. Please note that this will not work with a long Goat Guns barrel with the A2 front post, the front post must be removed. This hand guard works best with the short barrel and a suppressor (Shown in pictures). Do not over tighten bolts, as the plastic material will crack. This Item does not include the gun. Note, this will not fit directly with old Goat Guns models. Modification is needed for fitment with older models.
