Rock River Arms National Match Lower Receiver Parts Kit with 2-Stage Trigger for the AR-15

This Rock River Arms Complete AR-15 Lower Receiver Parts kit with National Match Grade 2-stage trigger will complete an mil-spec AR-15 lower. The NM 2-Stage trigger provides a crisp, 4 1/2 to 5 lb., 2-stage, trigger pull. The lightened trigger pull helps to improve accuracy, comfort, and consistent point of fire throughout the trigger pull. Sear engagement point is located behind the hammer to reduce pull weight. Low mass hammer speeds lock time. Rock River Arms is renowned for their National MatchTwo-Stage Trigger as being one of the crispest and cleanest "breaks" in the industry.
