Typically, barrels ranging from 18 to 24 inches are considered optimal for long-range AR15 builds, providing a good compromise between velocity, accuracy, and manageability.

Twist rate, on the other hand, refers to the rate at which the rifling in the barrel spins the bullet, and it’s expressed in terms like “1 in 7” or “1 in 9”, indicating one complete twist in 7 or 9 inches of barrel length, respectively. The twist rate is crucial because it stabilizes the bullet in flight, which is vital for maintaining accuracy over long distances. The correct twist rate for your AR15 depends on the weight and length of the bullets you intend to shoot; heavier and longer bullets generally require a faster twist rate to stabilize properly.

For long-range shooting, where heavier bullets are often preferred for their ability to resist wind drift and retain energy downrange, a faster twist rate is typically advantageous. A 1 in 7 or 1 in 8 twist rate is common for these applications, as they can stabilize bullets up to and beyond 77 grains effectively. It’s important to match the twist rate with your chosen ammunition to ensure the best possible performance.

Selecting the right barrel length and twist rate for your AR15 upper is a balancing act that requires consideration of your specific long-range shooting goals.
