Product Description
Williams Twilight Aperture Long Shank TW-1/2"x.093 For Low Light 1441WILLIAMS TWILIGHT APERTURE
Twilight apertures are designed for shooting under poor light conditions, early morning, late evening, and other inclement conditions. They create a sharp contrast that gives quick definition to the aperture hole, and they eliminate the "fuzz" with which many shooters have trouble. These apertures are perhaps the greatest development in metallic sights in the last three decades, positive sighting when the light is poor but the hunting best. Williams Twilight apertures will accommodate Redfield, Lyman, etc. NOTE: Long shank apertures for WGRS Receiver Sight are available only in the 3/8 x .093, 3/8 x .050, 3/8 x .125 and 3/8 x .150 sizes.
