The Nineball tight bore steel barrel for gas blowback handguns is the result of all the accumulated technologies and experience gathered from the Prometheus EG barrel series. The Nineball tight bore power barrel reduces the amount space around the BB to increase the overall air pressure behind the BB itself. Reducing as much possible air loss allows for the power barrel to achieve maximum performance.
