Rock River Arms National Match Two Stage Ultra Varmint Trigger Kit Features Rock River Arms manufactures this National Match trigger kit using an EDM or electrical discharge machining cutting process that produces extremely precise and consistent engagement surfaces on the sear and hammer. This level of precision is difficult to achieve with conventional machining and is a major contributor to the clean predictable break that separates a match grade trigger from a standard factory unit. The two stage design gives the shooter a distinct take up stage before reaching a crisp light final break a feel that many precision and varmint shooters prefer because it allows for more deliberate trigger control. This design is particularly well suited to shooters taking precise shots on small or distant targets where trigger control directly affects accuracy. Set to a 3.5 to 4 pound pull weight the trigger offers a noticeably lighter and more refined pull than the 6 to 9 pound range typical of mil-spec AR-15 triggers without dropping so light that it compromises safe handling in the field. This pull weight range suits varmint hunting and competitive shooting disciplines where follow up shots and precision matter more than rapid high volume fire. Installing a dedicated two stage trigger like this is one of the most effective upgrades an AR-15 owner can make to improve practical accuracy. Shooters building a dedicated varmint or precision rifle on the AR-15 platform will find this Rock River Arms trigger kit a worthwhile addition to their build.
