This SmythBusters video debunks the common internet myth of galvanic corrosion on AR-15 firearms. The Brownells Gun Tech duo, Steve Ostrem and Caleb Savant, explain that the non-conductive anodized and finished surfaces of AR-15 receivers and barrels prevent direct metal-to-metal contact. They consulted with top manufacturers like Sons of Liberty Gun Works and Geissele Automatics, confirming that lubrication of barrel threads is for torque, not insulation. The video concludes that causing galvanic corrosion on an AR-15 would require intentionally extreme modifications. Viewers are encouraged to share personal experiences or photos of suspected galvanic corrosion.
