Sinclair International AR-15 Bolt Vise Features The Sinclair International AR-15 Bolt Vise compresses the ejector so the spring pin can be removed easily without the ejector and spring launching off the workbench under spring tension. The tool cradles the bolt and holds it firmly in place while the screw assembly slowly releases that pressure giving the user full control during disassembly. A dedicated hole in the vise body allows the pin to drop free once compression is applied keeping small parts contained. This controlled process protects the ejector and spring so they can be reused or easily replaced during reassembly. Beyond ejector removal the vise can also hold the bolt securely while replacing gas rings or swapping out the extractor making it a versatile bench tool for bolt maintenance. Sinclair recommends replacing the ejector roll pin during reassembly and a 1/16 inch number 1 roll pin punch is required to drive the pin back out if needed. This tool is a practical addition for any AR-15 owner who performs their own cleaning and parts replacement rather than relying on a gunsmith. Reliable bolt maintenance keeps an AR-15 running smoothly and this vise makes that maintenance safer and easier at home.
