In Greek mythology, Prometheus created man-kind and stole the power of fire from Mount Olympus and gave it to man-kind. The Myth has little to do with this product but it is a cool story Prometheus-Airsoft would like to share with you. Nevertheless, this is an awesome AEG tight bore barrel favored by many.

Evike.com now distributes Prometheus products directly from Japan to bring you the newest version, factory direct.

"outstanding on my Krytac Trident Mk2 SPR. It shoots lazers! Will note, it is slightly a bit THICK! As such, only use ONE o-ring on the very last circle indent otherwise it will not fit into your outer barrel! Good luck!

"The model for the sig mcx works great paired with a 4aud bucking and the factory hopup unit. Getting great and consistent shots.

"Love it! Threw it into my LanTac SF15 with a MAXX hop up and maple leaf 60 bucking and it shoots like a dream. Really the best inner barrel for the MAXX hop ups. Super consistent FPS and aided the increase in range from the other upgrades. Highly recommend
