AR-10 Barrels

AR-10 barrels are the foundation of your rifle’s performance, directly affecting accuracy, velocity, and overall reliability. At Arm or Ally, we offer a diverse range of AR-10 barrels in calibers such as .308 Winchester, 6.5 Creedmoor, .243 Winchester, and the new .8.6 Blackout. Whether you’re building a precision rifle for long-range shooting or a rugged hunting setup, our collection of barrels ensures optimal performance tailored to your needs.

One of the most critical factors when selecting an AR-10 barrel is caliber. The .308 Winchester is a versatile choice for hunting and tactical applications, offering powerful performance and widespread availability. For long-range enthusiasts, the 6.5 Creedmoor delivers superior ballistic efficiency and accuracy, making it a favorite among precision shooters.

Recently, we’ve also expanded our collection to include the .243 Winchester, a caliber known for its flat trajectories, excellent accuracy, and manageable recoil. It’s perfect for varmint hunting and precision long-range shooting, providing a versatile and reliable option for your AR-10 build. Additionally, the .8.6 Blackout is a powerful and adaptable new caliber gaining popularity for tactical and long-range applications. With its ability to handle both supersonic and subsonic ammunition, the .8.6 Blackout offers the flexibility needed for both stealthy suppressed shooting and full-power tactical engagements. These calibers are well-represented in our inventory, allowing you to choose the best fit for your shooting requirements.

Barrel length and profile are equally important considerations. Shorter barrels provide maneuverability for tactical and close-quarters scenarios, while longer barrels enhance velocity and accuracy for long-range shooting. Our selection includes options from 16 inches to 24 inches, with profiles ranging from lightweight to heavy-duty, ensuring that every shooter can find the perfect barrel to complement their build.

Materials and coatings play a significant role in the performance and durability of AR-10 barrels. Many of our barrels are crafted from chrome-moly vanadium steel or stainless steel, delivering exceptional strength and longevity. Additionally, finishes such as nitride, phosphate, or stainless ensure resistance to corrosion and wear, maintaining accuracy and reliability even in harsh conditions.

Ballistic Advantage’s .243 Win and .8.6 Blackout barrels feature precision machining and tight tolerances, ensuring optimal performance for both long-range and tactical shooting scenarios.

Matching your barrel with the correct twist rate is another important factor for optimal performance. A twist rate like 1:10 is ideal for stabilizing heavier projectiles in .308 Win, while 1:8 twist rates excel with 6.5 Creedmoor. Our product descriptions include detailed specifications, helping you select a barrel that aligns perfectly with your ammunition and shooting goals.
