As the flagship model of Microtech’s OTF lineup, the Microtech Ultratech® sets the standard for OTF automatic double action. Proprietary technology allows the firing spring to be at rest in both the open and closed positions, drastically reducing wear on the internal firing mechanisms. The contoured chassis handle provides a lighter and more ergonomic feel and comes in a smooth, flat finish. The Ultratech auto fires and retracts with the thumb slider located on the side of the handle. The double action spring allows for one handed operation perfect for Military, LEO and first responders.
