What Are AR15 Upper Parts?

The AR-15 rifle is modular, meaning it can be broken down into two main sections: the upper receiver and the lower receiver. The upper receiver houses many of the most important components of the rifle, directly affecting accuracy, reliability, and caliber options.

Common AR15 upper parts include:

• Stripped Upper Receiver – The base housing unit that connects to the lower receiver.

• Barrel – Determines range, accuracy, and velocity.

• Bolt Carrier Group (BCG) – Responsible for chambering and cycling rounds.

• Charging Handle – Allows you to chamber rounds and clear malfunctions.

• Handguard or Rail System – Supports accessories like optics, grips, and lights.

• Gas Block and Gas Tube – Essential for proper cycling.

• Dust Cover and Forward Assist – Small parts that protect the action and enhance reliability.

Each of these parts can be purchased individually or as part of a complete upper assembly at GorillaMachining.com.

Why AR15 Upper Parts Matter

Your AR-15’s performance largely depends on the quality of its upper parts. Here’s why:

• Accuracy – A premium barrel and well-machined receiver dramatically improve precision.

• Reliability – Tight machining tolerances and durable coatings reduce malfunctions.

• Customization – Different handguards and rails let you add optics, lasers, or foregrips.

• Durability – High-grade aluminum and protective finishes resist wear and corrosion.

• Caliber Options – By changing uppers, you can shoot .223/5.56 NATO, .300 Blackout, 9mm, and more.
