This product is 100% made in the USA! All components are quality Mil-Spec parts for completing your AR15 lower receiver. Trust in BKF for a smooth hassle free build.

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.  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

    This should be your go to for a pistol build. Lpk has all friction points polished for a light crispy pull. Plus the sb tactical brace is superior over the others in my opinion for $99 you can’t beet it.
