Machined from solid alloy bar stock, the combo tool allows for easy removal of nipple and breech plug for cleaning. Slotted end removes nipple and screwdriver end removes breech plug. Specially drilled holes in tool hold the screwdriver in place for added leverage. The 9.5" tool extends 4" more than the standard tool so the breech plug can be removed without removing the scope. The Disc Combo Tool comes with C-ring.
