Description
The FAXON FIREARMS Duty Series is a rifle barrel in .300 AAC Blackout, 10.50" long.
The rifling twist is 1:8 – one full turn of the bullet in 8 inches of barrel. Twist rate decides which bullet weights a barrel can stabilise: a faster twist (a smaller number) handles longer, heavier bullets, a slower one suits lighter ones. It is cut into the barrel and cannot be changed.
It is chambered in .300 AAC Blackout. Chamber and bore have to match the ammunition exactly – a barrel is not adaptable to another cartridge.
Fitting a barrel is gunsmithing on most actions: headspace has to be checked with gauges after installation. An AR-pattern barrel is the usual exception, being a drop-in against a correct bolt.
This is a part or accessory, not a firearm, and ships directly to your address.
