I like the ghost ring system, but I have found out getting a set for my mossberg is kind of pricey. I don't know what kind of shotgun you have but I can get a set from Mossberg for around $80. then I would have to go to the gun smith and have him silver solder the front one onto the barrel, which I got a $100 estimate. So that's a $180 sighting system. Seems a bit pricey, I should have bought a 590a1.
