Includes AR grip screw, washer and roll pin for permanent installation of fin. Made of glass eninforced high composite polymer. The divider that mades it a SS grip is offset to the left for better control. This grip is for right handed use only. Although it includes a backplate that lets you convert it to a normal grip, we highly recommend you utilize the included roll pin and make it a SS grip in a semi permanent manner. If you exit the state and want to revert back to a standard pistol grip then it would be easier for you to simply retain your original grip and install that as opposed to converting this one back to a standard grip.
