The Pure Precision SKLTN Stainless steel action complements and improves on the original Summit action. They kept the base features of the Summit action and expanded on some key features to set the SKLTN model above and beyond, making it very light and feature rich. To decrease weight there are lightening cuts in the body, recoil lug and a trimmed bolt shroud. A new spiral fluting pattern in the bolt also helps to decrease weight.
