ELG stands for 'Enhanced Longitudinal Grind'. Our new lower parts kits have set the standard when it comes to out-of-the-box mil-spec performance for Original Equipment Manufacturers. At the heart of this kit stands the longitudinally-ground trigger, which is machined in-line with the direction of pull along the long axis of the trigger. What results is a 32RMS finish or better, which provides two significant advantages over standard mil-spec kits: a smoother pull with reduced grittiness, and an enhanced starting platform for performing a trigger job. All black parts in the kit are phosphate coated. We do not use coatings that will rust over time like black oxide.
