One Horse AR15 Complete Lower Parts Kit

The One Horse AR15 Complete Lower Parts Kit (part no. OHLPK0) bundles the internal components needed to finish a stripped AR15 lower receiver, so builders aren’t sourcing a trigger group, springs, pins, and a pistol grip separately. One Horse packages this as a mil-spec-compatible kit for standard AR15 lower builds.
