Complete AR-15 Mil Spec Lower Parts Kit (LPK)

At the heart of this kit stands the longitudinally-ground trigger, which is ground in-line with the direction of pull along the long axis of the trigger, and then finish-polished. This grind and polish provide two significant advantages over standard mil-spec kits:

• A smoother pull with reduced grittiness
  
• An enhanced basis for performing a trigger job
