Sons of Liberty Gun Works E-Blaster Guts AR-15 Lower Parts Kit

Sons of Liberty put the good parts in one bag here. The Liberty two stage trigger is the centerpiece, with a B5 pistol grip and an ambidextrous safety selector filling out the controls. The rest is the hardware a stripped lower needs: takedown pins and assembly, magazine catch and assembly, bolt catch and assembly, and the buffer retainer pin and spring.

A two stage trigger takes up slack on the first stage and breaks on a shorter, cleaner second stage, which is easier to shoot precisely than a standard issue single stage. SOLGW states its small parts fit most mil spec firearms, so this goes into a bare lower from most makers without drama.
