The LayLax Nine Ball tight bore stainless steel inner barrels for gas blowback handguns are the result of all the accumulated technologies and experience gathered from the Prometheus EG barrel series. The Nine Ball 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.  Adding to the existing performance and quality, our ultra-tight bore boasts a 6.00mm diameter which gives your pistol an automatic power boost! 

Includes: 

• Umarex G19 Power Barrel (85mm)(&phi6.00mm) x1

*NOTE: This is an ULTRA-TIGHT bore inner barrel and requires higher quality, match grade BBs to ensure smooth operations which minimizes jamming or malfuctions due to uneven sizes of cheaper BBs.
