  • Compatibility is described for mil-spec AR lowers and standard components, so non-standard setups may need extra verification before purchase.
  • The finish and material are specified, but no performance claims beyond wear resistance are provided, so expectations should stay centered on the listed construction details.
  • Black models may vary in marking style, with options noted as laser-engraved T-marks and an American flag on the Picatinny rail, or T-marks only.
