Considerations & Trade-offs

  • This is a stripped upper receiver, so it does not include the other components needed to complete a rifle upper assembly.
  • Compatibility is described for mil-spec AR lowers and standard components, so fit should be verified against any non-standard parts in your build.
  • The black version is offered with either laser-engraved T-marks and an American flag on the Picatinny rail, or T-marks only, so the exact rail marking style may vary.
  • It uses .250" pivot and takedown pins, which means it is intended for builds that match that pin size.
