The Exact Edge Extractor is manufactured through an EDM process to produce exacting tolerances. The new extractor will not lose its edge under impact. The extractor features a very precise hook point. It is hardened to a RC 58-60 to withstand years of use and still maintain its edge. We are able to hold the tolerances to +/-.0001" by utilizing the EDM manufacturing process. Replaces Remington part #16176 and fits 870, 12, 20 and 1100, 12, 20. Mfg: Volquartsen SPECS: For Remington 870 and 1100 models.
