E2 Armory TIN BCG - Great or Gimmick Coating Titanium Nitride
This video from E2 Armory reviews their Titanium Nitride (TiN) coated Bolt Carrier Group (BCG). The description delves into the science and benefits of TiN coating, including improved wear resistance, reduced friction, and enhanced corrosion protection due to its nanocrystalline structure. It details the specific materials and manufacturing processes for each component of the BCG, emphasizing USA-made parts, HPT/MPI testing, and a micro-polished finish. The video aims to determine if this advanced coating is a significant performance upgrade or merely a cosmetic gimmick.
