The AR-10 platform has earned a reputation for delivering power, accuracy, and versatility. A critical component of any AR-10 build is the upper assembly, which plays a significant role in determining the performance and reliability of your rifle.

At Moriarti Armaments, we offer complete AR-10 upper assemblies designed for shooters who demand performance and value. This guide will cover what makes a complete upper so important, what to consider when buying one, and how Moriarti Armaments stands out in the market.


What is a Complete AR-10 Upper Assembly?
An AR-10 upper assembly is the upper portion of the rifle, housing the barrel, handguard, gas system, and other essential components. Unlike a stripped upper, a complete upper assembly is fully assembled and typically includes:

  • Upper receiver

  • Barrel

  • Gas block and gas tube

  • Handguard

  • Muzzle device

  • Bolt carrier group (BCG)

  • Charging handle

These assemblies are designed to fit seamlessly with your lower receiver, saving you time and ensuring reliable performance.


Why Choose a Complete Upper Assembly?
There are several reasons why builders prefer complete upper assemblies:

  • Eliminate Compatibility Concerns: All components are assembled and tested together for proper fit and function.

  • Save Time: Skip the process of sourcing and assembling parts.

  • Reduce Costs: Complete upper bundles typically cost less than buying each part separately.

  • Improve Reliability: Factory-assembled uppers minimize potential issues and deliver consistent performance.
