I've had the chance to use ghost rings on an 870 and and 1187, and I've got some time with just a bead sighted shotgun. I liked both, but find that my accuracy with the bead sights is less than what I'd like, but the ghost ring ramp front sight (a Scattergun tech) was a bit large. Are there any ghost ring sights that use something like a bead as the front sight? Does Ashley Express make one of these, as it seems to fall in line with what they do?
