Big dot easy to see in all light conditions - XS Sight Systems Big Dot Tritium for Shotgun

The installation is very easy to do. I had some acraglass on hand, so i didn't have to buy an adhesive. It is a very solid mount. The height is slightly higher than the bead it replaced, but I noticed no difference in point of impact when patterning. The sight is easy to pick up in twilight and darkness and allows proper indexing of the gun before you turn the light on to positively identify the target. Daytime, the big white dot is easy to see and stands out against most all backgrounds.
