Ballistic Company - AR-15 M4A4 Stripped Upper Receiver - Class 3 Anodized
When it comes to building or upgrading an AR-15 platform, the upper receiver is one of the most crucial components that determines performance, reliability, and overall shooting experience. The Ballistic Company AR-15 M4A4 Stripped Upper Receiver - Class 3 Anodized has quickly become a top choice among firearm builders and enthusiasts due to its superior craftsmanship, durable anodized finish, and compatibility with mil-spec components.
Whether you are creating a new custom build or enhancing an existing rifle, this stripped upper receiver delivers strength, precision, and a clean foundation for your AR-15.
What is a Stripped Upper Receiver?
A stripped upper receiver is the bare housing for the AR-15’s critical components. Unlike a complete upper receiver, which comes pre-installed with the barrel, bolt carrier group, and charging handle, a stripped upper is an unfinished canvas.
This allows builders to:
-
Choose their own barrel length and profile.
-
Customize gas systems.
-
Select optics and handguards that suit their shooting style.
-
Create a personalized AR-15 that balances accuracy, weight, and performance.
The Ballistic Company M4A4 stripped upper receiver provides the perfect foundation for a precision or tactical build.

2. Class 3 Hardcoat Anodizing
The Class 3 anodized finish provides superior corrosion resistance, hardness, and wear protection compared to standard coatings. This means your upper receiver can endure thousands of rounds, adverse weather, and rugged conditions without losing its sleek finish.
