The Tac-Cap replaces the standard plastic cap at the bottom of Accu-Shot's actuator knob. Made of steel, with a profile similar to the standard plastic cap. The Steel Tac-Cap will add durability and is recommended for hard use applications. It friction-fits, no tools required. However, we recommend permanently setting the Tac-Cap and will do so at no additional charge when ordered along with any Accu-Shot. Black only. Made in the U.S.A.
