Adopted in the early to mid 2000s due to multiple benefits: Mil-Spec Formulated to meet MIL-PRF-21164G and NATO G-353 standards — the same extreme-pressure specs used in military aviation. Trusted by armorers, gunsmiths, and professionals around the world. Wear & Friction Protection Infused with molybdenum disulfide (MoS₂) to reduce metal-on-metal wear in high-stress contact points like bolt carrier groups, locking lugs, and rails. Won't Sling, Burn, or Melt Designed for high heat and heavy fire — AeroShell 64 stays in place, even during suppressed shooting, full-auto fire, or extended range days. Corrosion and Oxidation Resistant Protects internal firearm components from rust, moisture, and oxidation — ideal for humid environments, long-term storage, and marine use. Extended Service Life Unlike thin oils that evaporate or run, this grease offers long-lasting lubrication with fewer applications required. Smoothed Action and Cycling Enhances overall firearm performance by reducing resistance and chatter — ideal for tuned AR platforms and precision-built firearms.
