NZ Armourer uses the same high standard of machining practice whether you are replacing a worn barrel on a hunting rifle or fitting a barrel to a custom built rifle, regardless of make, operating system or configuration. All barrel work is carried out on a heavy duty cast bed lathe, with the work piece being held through the headstock. The bore 2 inches in front of the chamber throat is dialed true to provide the projectile with a straight start into the rifling. The muzzle end of the barrel is machined using the same process too.
