Uncle Mikes magazine cap swivel sets have a factory magazine cap with the swivel base already installed. Just unscrew the factory magazine cap and replace it with the new cap. For the buttstock, a 3/4 inch wood screw swivel base is included, along with two super swivels with tri lock. This is for a 20 gauge shotgun.
