RISE Armament ICONIC Independent Two-Stage Trigger Graphite. One crisp break. The ICONIC Independent Two-Stage Trigger combines the awareness feedback and flexibility of a two-stage trigger with the responsiveness crispness and speed of a single-stage trigger. On other two-stage triggers the stages aren't independent. The same basic parts interact at both stages which can limit performance. But the stages on an ICONIC Independent Two-Stage Trigger have separate mechanical components for each stage. This allows a distinct "wall;" a crisp clean second-stage break (comparable to a high-performance single-stage trigger); virtually no overtravel; no creep; and without the inherent mushiness felt in standard captive two-stage triggers.
