Choosing the correct Bolt Carrier Group (BCG) is crucial for AR-15 reliability and longevity. Key considerations include the steel type (Carpenter-158 vs. 9310), manufacturing processes like shot peening and case hardening, and quality control tests such as MPI and HPT. Different coatings offer varying benefits, and understanding their impact on tolerances is vital for optimal performance. Enhanced features can further improve reliability.

This video from AT3 Tactical provides an expert-level breakdown of Bolt Carrier Groups (BCGs) for AR-15 platforms. Instructor C.J. details the critical role of BCGs, explaining how material composition (Carpenter 158, 9310, 8620 steel), advanced coatings (Phosphate, Nitride, Nickel Boron, DLC), and special features like full-auto profiles and properly staked gas keys influence performance and price. The content is highly technical, utilizing metrics like tensile strength (MPA) and coefficient of friction (COF) to guide consumers toward informed purchasing decisions.

This guide covers the installation and assessment of Aero Precision's PRO Series barrels and BCGs. It delves into the technical specifications, including materials like 41V50 steel and 9310 bolt steel, and compares them against industry standards and competitors like Expo Arms.
