Fierce Firearms 2841824 7mm 24″ Fits AR-15

Description

The Fierce Firearms 7mm is a rifle barrel, 24" 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.

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.
