Choosing the correct AR-15 barrel is paramount for accuracy, durability, and reliability. Key factors include defining the rifle's purpose (General Purpose, Long Range, CQB) as this dictates trade-offs in barrel length, profile, material, and gas system. Understanding legal barrel lengths and configurations (SBRs, pistols) is crucial, as is selecting appropriate materials like 4150 Chromoly or 416R Stainless Steel with protective linings such as chrome or Nitriding. Barrel profile impacts heat management and handling, while rifling methods and gas system length affect performance and tuning.
