Tested and influenced by gunsmiths, the Armorer's Master Hammer is a 20-ounce, 9-1/2" long, forged hammer with full-length tang for a perfect balance and ideal ergonomics for precise control. A removable soft blow hammer head cover and interchangeable hammer heads with integrated storage makes it easy to install the correct hammer head for the application. Stored in the handle is a removable, stainless steel, magnetic pin starter to provide a helping hand when building or modifying firearms.
