The Geissele Stressproof bolt assembly comes complete with the extractor installed. Geissele's Stressproof bolts are an upgraded replacement for standard AR bolts. Confirm caliber and platform for your rifle, since the listing does not state them. If you are not comfortable working on the internal parts of your firearm, have a qualified gunsmith handle the installation.
