Knobloch Lens Holders are available in various types for all the sport shooter’s requirements. The large 37mm lens holder is recommended for the pistol shooter. The small 23mm lens holder is often a better choice for the rifle shooter because it’s easier to adjust behind the diopter.

The small lens holder is also available bent at an angle, to bring the lens 8mm closer to the eye compared to the straight version.

The lens holders are sized to match optional filter and clip-on-holders. They can also be used with an iris shutter or centering device by simply attaching it to the holder.
