The Prometheus 6.03 EG precision barrel is a steel inner barrel that offers an exceptionally high-quality and durable upgrade for your replica. Thanks to its tight and consistent 6.03mm inner diameter, BBs travel straight and stable without unnecessary deviation. Unlike standard brass barrels, the steel construction minimizes vibration and movement inside the outer barrel, which can otherwise significantly affect accuracy. Prometheus precision barrels are well-known for their outstanding quality, especially the smoothness of the inner surface.
