These 2-stage national match lower parts kits are one of the most reliable kits for your AR-15. All parts are mil-spec and have lasted for many thousand rounds and in all types of weather. YES, these have the 2-stage NM trigger kits included. Why buy a lower parts kit then buy another trigger separately? Get these and you are done! The fit and quality are #1. If it's good enough for some of our heros overseas, it's good enough for me!
Mil-Spec Lower Parts Kit with a 2-stage NM trigger kit from Rock River Arms. Comes with A2 Black Grip.
