Prometheus EG 6.03 Precision Barrel - 185 mm
EG Barrel series precision barrels by Prometheus are compatible with a majority of AEG replicas.
Barrels from this series are considered to be one of the best precision barrels on the market. This is due to the barrels having a low deviation regarding caliber differences on the inside of the barrel and undergoing a rigorous quality assurance. Barrels are made in Japan and are manufactured in a very precise way from stainless steel.
EG Prometheus barrels are also much more even, stable and definitely straighter on the inside than a majority of other products available on the market.
We recommend using precision barrels only with precision BBs for a peak performance.
