This video explains the patent-pending self-locking pins used in the Variable Interface System (VIS) for optics mounting. The description highlights how these pins create an advanced optics mounting system by exerting lateral pressure on the optic's interior mounting surface as screws are torqued. This process eliminates variance and left/right movement, resulting in a superior fit between the firearm slide and a wide array of optics.
