One Horse AR-15 Complete Lower Parts Kit Features The One Horse AR-15 Complete Lower Parts Kit brings together every internal component a mil-spec lower receiver needs to function precision machined for drop-in compatibility. The kit covers the full fire control group including the single-stage mil-spec trigger trigger spring hammer and hammer spring disconnector and disconnector spring along with their respective pins. It also includes the selector selector detent and spring bolt catch assembly magazine catch assembly takedown and pivot pins with detents and springs and the buffer retainer and spring. Builders get a trigger guard with its roll pin and a bolt release roll pin as well leaving nothing missing but the buffer tube assembly and stock. The phosphate coating on the trigger group resists wear and corrosion while keeping the 5.5 to 7 lb pull weight consistent over repeated use. An A2-style pistol grip with its mounting screw and lock washer rounds out the kit giving the lower a complete ready-to-shoot ergonomic package straight out of the box. Every part is machined to mil-spec tolerances so the kit drops into any standard mil-spec AR-15 lower without fitting or modification. For a home builder assembling a lower from a stripped receiver or an owner refreshing worn internals this kit delivers a complete reliable rebuild in one package.
