Guarder 6.02mm Interchange Precision Barrel 650mm

The Guarder 6.02mm Interchange Precision Barrel 650mm is made of copper and of very good quality.

Copper is a softer material than stainless steel and can therefore be damaged faster than a stainless steel barrel. Think for example if a grain of sand accidentally got into the barrel. With its diameter of 6.02mm, it is a nice precision barrel, however, it needs to be treated with care and love. Careful cleaning and maintenance of this barrel is a must.
