The GG&G line of Receiver End Plate Sling Adapters for tactical shotguns and the M16/AR15 series has been expanded to include the AR15/M16 fixed stock model. Many operators prefer the M16/AR15 with a fixed stock as it provides a somewhat more stable firing platform. Installation of this unique accessory is easily accomplished, requiring removal of the fixed buttstock and installation of the new GG&G end plate, adapter spacer and longer screw. This lightweight accessory weighs in at less than one ounce.
