Noveske Rifleworks has ceased selling 300 Fireball barrels and instead will be shipping .300 AAC BLK barrels for the AR-15. The barrels have an attractive stainless steel bead blast finish, a medium contour, 1:8″ twist, include an installed gas block and will be offered in 10″ and 16″ lengths. The 10″ is selling for $365 and the 16″ for $455.

Noveske says on their website that certain Noveske 300 Fireball barrels will safely fire the .300 BLK …

300 AAC BLACKOUT ammunition is safe to use in Noveske 300 FB barrels with a serial number of 290000 and higher.

Noveske 300 FB barrels with a serial number less than 290000 or without a serial number will need to be checked before using 300 AAC BLACKOUT ammunition. We will be setting up a program to send in older barrels for inspection and reaming if needed.
