Bright Barrel ReturneR 6.05
Precision Barrel – 455 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 brass.

Prometheus barrels are also much more even, stable and
definitely more straight 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.
