A further development in the new style of 'open' front sights

The new designed front sight holder Race is an alternative to the traditional system
It has some new aiming characteristics
The design of the holder in connection with the free floating plastic front sight is very comfortable for the eye

The holder system has no disturbing front sight tunnel ring, which distracts the eye.
The target image is detected fast and centered quickly.
With the second free floating plastic ring, called Empty Ring, you can easily control the centering of your rear sight.
The empty ring relieves the eye and makes target acquisition easier.
Also available as a separate accessory, with a black Contrast Ring. (Illustrated on the black sight but not included)
Instead of the rings you also can use an optical lens or you leave it empty

Please note: each sight ships with an Empty Ring, but no inserts or lenses
The sight also ships with spacers to allow it to be fitted to Anschutz, Bleiker, Walther, FWB & Hammerli dovetails
