This tool is designed to compress and control the ejector on Remington style bolts. The tool compresses the ejector and then turns to engage the locking lugs to hold the ejector in a compressed position. This allows you to drive the pin out and remove the ejector and spring in a controlled manner. Invaluable tool to have when replacing or shortening the ejector spring.
The tool includes quick change fittings for small bolt faces, .222 thru .223, etc. and large bolt faces, .308 thru Magnums, etc.
