Tightbore 6.03mm EG Precision Barrel 363mm 

EG Barrel series precision barrels by Prometheus are compatible with majority of AEG replicas.

Barrels from this series are considered one of the best precision barrels on the market. This is due to the barrels having low deviation regarding caliber differences on the inside of a barrel and undergoing rigorous quality assurance. The barrels are made in Japan and are manufactured in a very precise way from stainless steel.

EG Prometheus barrels are also much more equal, stable and definitely more straight on the inside than majority of other products available on the market.

We recommend using precision barrels only with precision BBs for peak performance.
