When I look through it the front sight is really sharp, as is the target. It's a bifocal eye's dream. In good daylight the 1/8" aperture gives you a really fine sight picture.

Took it out at dusk yesterday evening and sighted on my neighbor's dog about 60 yards away with none of the inserts in place, just the 3/8" nut. Man, it looked good, except the blue front sight was a little hard to pick up. I suspect the LOL rear sight and a fiber optic front sight will be just the ticket for hunting. Can't wait for the next range session - probably next week end.
