bremnet says... It's considered to be a very reliable and long lasting action. The fit and design keep the action "tight" through repeated use and reduces wear on mating surfaces. A larger-than-most extractor claw reduces the possibility of stuck rounds from breaking the claw or slipping out during extraction. A noticeably smoother action when chambering or extracting a round. I don't know that it contributes to the accuracy of the rifle, would say not in my experience, but opinions vary.
