During the barrel assembly cleaning, what is done first to remove loose firing residues?

Using a cleaning rod with a patch soaked in CLP (Cleaner, Lubricant, and Protectant) is the correct approach for initially removing loose firing residues during barrel assembly cleaning. This method effectively allows the solvent to penetrate and break down carbon buildup, powder residues, and other contaminants that may have accumulated inside the barrel. The soaked patch is specifically designed to get into the crevices and fouling effectively, making it a necessary first step in the cleaning process.

While wiping the barrel with a cloth can help remove surface dirt and residues, it might not be as effective in breaking down the built-up contaminants compared to using a CLP-soaked patch. Rinsing the barrel with water could damage the internal parts or leave residue if not dried properly, and soaking the barrel in CLP without the mechanical action of a patch would also not address the residues effectively. Thus, using a cleaning rod with a patch soaked in CLP is a preferred method for achieving thorough cleaning of the firearm's barrel.
