Quick Tip: The Difference Between Nitrided & Chrome-Lined Barrels
This video explains the key differences between nitrided and chrome-lined barrels for AR-15 builds. Brownells technician Caleb Savant details how both finishes offer corrosion protection, reduced bore wear, and extended barrel life. Chrome lining is highlighted for its superior heat and friction resistance, making it ideal for full-auto or high-volume semi-auto fire. Nitriding, also known as Melonite or QPQ, is presented as a more cost-effective option due to easier application. The video concludes that the choice depends on the intended use of the firearm, with both providing excellent service.
