AR-15, AR-10, and M16 barrels are used to define caliber compatibility, barrel length, gas system setup, and overall shooting performance on compatible rifle platforms. They are commonly chosen for new builds, repairs, replacements, and upgrades where accuracy, handling, and intended use matter. Different barrel options can affect velocity, weight, balance, heat management, and application depending on the rifle setup. This category includes barrels built for proper fit, dependable function, and practical performance across AR-platform rifles.
