AR10 Upper Parts

AR10 Upper Parts

AR10 Upper Parts comprise a vital category for firearm enthusiasts and builders focusing on customizing or maintaining their AR10 rifles. These components are integral to the upper assembly of the rifle and include parts such as the upper receiver, barrel, bolt carrier group, charging handle, handguard, gas block, and gas tube.

  • Upper Receiver: The primary housing for the AR10’s bolt carrier group and barrel, often available in forged, billet, or polymer variants.
  • Barrel: Available in various lengths, materials, and finishes, the barrel directly influences the rifle’s accuracy, range, and overall performance.
  • Bolt Carrier Group (BCG): A critical component for the cycling of the firearm, ensuring reliable operation and proper ejection of spent cartridges.
  • Charging Handle: Used to manually cycle the action of the rifle, available in ambidextrous and extended versions for enhanced functionality.
  • Handguard: Provides a secure grip, protects the hands from the heat of the barrel, and offers mounting points for accessories such as optics, lights, and bipods.
  • Gas Block and Gas Tube: Essential for the direct impingement gas system, controlling the flow of gas from the barrel to the bolt carrier group to cycle the action.

Whether upgrading for performance, customizing for aesthetics, or ensuring reliability, AR10 Upper Parts offer a wide range of options to meet the diverse needs of firearm users.
