The Brownells Bolt Ejector Tool is a tough, steel clamp that captures the bolt head, and the large-handled turnscrew depresses the ejector so the ejector pin can be safely removed or installed. The complete set includes turnscrews to fit both standard and small bolt faces; also included are separate bolt head retainers. The Brownells Bolt Ejector Tools work on bolts with plunger-style ejectors and forward-positioned locking lugs only. Instructions are included with the either the complete set or just the tool.
