Grizzly T10892 - Viper Chambering Truing Fixture
Simply hold this unique fixture in a 4-jaw chuck and use any two rings of four brass-tipped set screws to clamp your barrel in place. The middle ring of screws is placed ideally for setting up pistol barrels for chambering. It's like having two 4-jaw chucks to achieve perfect axial alignment of the bore prior to chambering. The fixture is machined with a slot along one side which allows for bolt and bolt face truing. Remington actions can also be trued up in the same fixture. An amazing innovation for dedicated gunsmiths looking to up their game!
