Universal bench block by Homestead Firearms. It is made from a non marring heavy duty multi-colored plastic, alittle softer than a metal or very hard plastic. This block can be used for disassembly of virtually any action. There are several features designed into this block specifically formainspring removal, drifting the rear sight, staking the front sight and dressing the side rails and many more. We use this while working on Winchester rifles all day long.
