Prometheus EG barrels are generally considered to some of the best tight bore barrels on the market. That is because these barrels have tight tolerances and meticulous quality control. These are all manufactured in Japan, and Laylax has a very good reputation for making quality barrels.

The inside of the bore is consistent and is straighter than typical Chinese barrels. The crowns and windows of these barrels are also well machined.
