I have clean several firearms with regular cleaners and lubricants, then I have cleaned with the AMSOIL product. There is a distinct difference in how the firearm behaves after cleaning and lubricating with your product. I notice the metal to metal sliding action is MUCH quieter and much more smooth. The AMSOIL product also lasted longer in storage that the conventional lubricant. The conventional lubricant left behind a residue that no longer provided metal to metal protection.
