TYRCHEM C4G BARREL CLEANING FOAM 200ml

Barrel cleaning foam with a propellant tube. It was created for those seeking professional level care for their weapon. It penetrates all areas of the barrel and gas mechanism, cleaning all residues of gunpowder, lead, and copper.

It actively cleans rust and forms an anti-corrosive film. An interesting innovation is that it changes color from white to blue when it encounters residues from shooting products.
