Rock River Arms AR-15 Two Stage Lower Receiver Parts Kit AR0120NM.

The AR0120NM by Rock River Arms features their Two Stage Trigger group which generally improves accuracy by lightening and smoothing out the trigger pull. The weight of pull on these are factory set and usually around 4 1/2 to 5 pounds. The two stage trigger takes out the "unknown" point of fire from the trigger stroke. This kit also includes a basic black A2 pistol grip and it will work with any standard AR-15 lower receiver.
