The Powder River Precision lightweight sear is CNC machined out of 440C Stainless Steel Bar stock and heat treated to 53-56 RC. The proprietary geometry helps to lighten the weight of the sear and lower the trigger pull weight. When properly installed it should result in a smooth trigger pull around 5 pounds. The grip safety engagement surface on the sear has been increased as well.
When used in conjunction with the BRZ trigger, the result is a clean, short trigger press with minimal pre-travel.
