Aero Precision 5.5″ 9MM CMV Barrel

APRH200072C – The Aero Precision 5.5″ 9mm barrel is perfect for your AR9/PCC/EPC build. Machined to mil-spec standards from 4150 CrMoV Steel and a QPQ corrosion-resistant finish, this 5.5″ barrel provides a solid foundation for your PCC build.

  • Designed to work with Glock-style AR builds
  • Compatible with most hollow point bullet designs
  • Compatible with EPC upper receivers, as well as standard mil-spec upper receivers
  • 9mm on an AR15 platform operates by blowback and does not need a gas block or gas tube
  • Threaded 1/2×28 to give you versatility when choosing a muzzle device
  • Integrated barrel extension Since the “barrel extension” is an integral part of the barrel, the length stated is the true overall length.  For example, an 11″ 9mm barrel has the same outer dimensions/length as a 10.5″ 5.56 barrel.
  • IMPORTANT: A standard 1/2×28 flash hider will not have enough clearance for a 9mm round to pass. Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore.
  • *NOTE: You may experience poor feeding performance with certain Winchester hollow point designs.”

NOTE: As of 1 April 2024, all Aero Precision barrels will be marked as manufactured by Ballistic Advantage and will include the Ballistic Advantage engraving. For more information, please click here.
