Precision extruded from aircraft grade aluminum and bonded with non-marring urethane.
The urethane coating is specially designed to provide a protective layer for the barrel's finish while providing extraordinary gripping abilities. Three different barrel openings of .85";, .66"; and .53"; will accommodate anything from an AR pencil barrel up to a bull barrel.
When inserted in a vise the urethane coating squeezes down tightly on the barrel to fully secure it for the forces needed for installation/ removal.
