IMPORTANT NOTICE FOR BARREL CLAMP PURCHASERS: The GG&G Barrel Clamp makes contact with your barrel and the GG&G Magazine Tube Extension. This contact may damage/wear the finish on your barrel or mag tube during usage. We recommend using masking tape applied to the inside of the GG&G Barrel Clamp where it makes contact with the barrel. It is not advised to apply any tape to the inside of the barrel clamp that makes contact with the Mag Tube Extension.  Since GG&G Inc. cannot control the installation of this product, GG&G will not be responsible for any wear, blemishes, marks or damage that may occur to your shotgun.
