Tough, steel clamp captures the bolt head, and the large-handled turnscrew depresses the ejector so the ejector pin can be safely removed or installed. Set includes turnscrews to fit both Standard and Small bolt faces; also included are separate bolt head retainers. One will fit bolt bodies up to .720" diameter (standard and small bolt face) and the other will fit AR-15/M16 bolts only. Complete AR-15/M16 Bolt Ejector Tool also available separately. Tools work on bolts with plunger-style ejectors and forward-positioned locking lugs only. Mfg: Brownells SPECS: Steel, blued. Plastic handle. Includes instructions.
