The Carter EZ release is based from the handle geometry and jaw position of the new revolutionary hinge, the NV. This release allows you to have the same feel when switching between the two releases and complement each other, but the magic doesna; (TM)t stop there. The EZ has a very unique feature in a thumb trigger, there is no travel adjustment! Controlled Engagement System (C.E.S.) design completely eliminates the need for a travel adjustment with absolutely no felt movement in the trigger. There is a trigger tension adjustment that allows you to customize the weight of your trigger.
