This is an exchange program. You send in your Kriss Vector trigger pack to be upgraded to a Double Tap Trigger pack. FREE RETURN SHIPPING.
The Double Tap Trigger allows the shooter to fire a round when the trigger is pulled and released. Unlike a factory trigger that only fires when the trigger is pulled. This trigger is a pull and release trigger only. Not a select fire. Safe/Double Tap Only. NOT a 3 position trigger. Must use all parts that are included. Do not alter in any kind of way.
