Complete pin set for the Echelon™ Variable Interface System.
The Variable Inface System (VIS) employs patent-pending self-locking pins to complete the most advanced optics mounting system on the market. As the mounting screws are torqued to spec, the pins exert lateral pressure on the optic’s interior mounting surface to eliminate variance and left/right movement. The result is an unparalleled fit between the slide and a wide variety of optics.
Includes Pin Set 1, Pin Set 2 and Pin Set 3.
