The Aero Precision .224 Valkyrie Bolt Carrier Group for AR-15 rifles is made from high quality materials with quality assurance measures like high pressure testing and magnetic particle inspecting. The bolt assembly is machined from Carpenter 158 tool steel and tested to ensure it can withstand thousands of high-pressure rounds. The Carrier assembly is machined from 8620 steel and the entire BCG is magnetic particle inspected to ensure every dimension is as precise at can be. The black Nitride finish increases hardness and creates an extremely smooth surface for ease of cleaning and improved reliability. If you want to build a no frills, reliable duty rifle, you can’t go wrong with this Aero Precision BCG.

Other areas that Aero Precision has focused on to improve the reliability of this M16 bolt carrier group is the chrome lined internals that come into contact with high pressure gases to prevent premature deterioration of critical components. The gas key has been staked, preventing it from coming loose over time and the bolt face has been shot peened to improve durability. Shot peening is the process of literally deforming the smooth surface in order to create more surface area and relieve stress to reduce the number of micro cracks from forming after many years of use.
