Product Description

The Aero Precision AR-15 Complete Upper (APAR505611) is the same upper receiver assembly found in the Aero Precision M16A4 Special Edition Complete Rifle, bringing military-inspired performance to your build. Chambered in 5.56 NATO with a 20-inch barrel, this complete upper delivers reliable, full-rifle-length accuracy and the classic A2 aesthetic that serious shooters appreciate. The barrel is manufactured from 4150 Chrome Moly Vanadium steel with a QPQ corrosion-resistant finish and a 1:7 twist rate for outstanding bullet stabilization across a wide range of projectile weights. An A2 Detachable Carry Handle and a pinned A2 Front Sight Block with bayonet lug round out the traditional configuration, while a rifle-length gas system and standard A2 flash hider complete the package. Note: this complete upper does not include a Bolt Carrier Group (BCG) or Charging Handle.

Product Highlights

  • Classic M16A4-Style Configuration: Replicates the upper receiver assembly used in the Aero Precision M16A4 Special Edition Complete Rifle for proven military-grade performance.
  • 20-Inch 5.56 NATO Barrel: 4150 Chrome Moly Vanadium construction with a QPQ corrosion-resistant finish and 1:7 twist rate for exceptional durability and accuracy.
  • A2 Iron Sight Package: Includes a detachable A2 carry handle rear sight and a pinned A2 Front Sight Block with bayonet lug for traditional, battle-proven sighting.
  • Rifle-Length Gas System: Provides a smoother, more consistent cycling experience with reduced felt recoil compared to shorter gas systems.
