Hi PAhunter86,

I have a Williams peep rear with a fiber optic front mounted on a Marlin 1894 .44 Magnum. It works great in heavy cover and low light. I know you want it for a shotgun....but I don't know why it wouldn't work as well mounted on a shotgun. Just sight it for the center of the pattern! (As a matter of fact I'm thinking of having my rifled slug barrel so equipped!)

Good luck!
