Using top quality components from their entirely in-house produced cold hammer forged barrels, lightweight free float DDM4 quad rail handguards, and better than MIL-SPEC M16 bolt carrier groups means that you're getting one of the best uppers available for the AR-15.

  • M16 cut MIL-SPEC bolt carrier group with properly staked gas key and chrome lined bore.
  • 12" DDM4 free float quad rail handguard provides plenty of accessory space and includes 3 santoprene rail covers.
