Williams Fire sights Universal Vent/Rib "Slugger" problem.

[Gutsdozer]

Hello,

I have not had a lot of time with work and family to sight in my Remington 870 with my new Wiliams Fire Sights. They are universal fit for vent/rib shotguns. They do fit but...they do not adjust low enough. At 40 yards my left and right are dead on but I am a good 12-14 inches low. The sights have no more adjustment. Everything is lined up properly. I have used the correct set of holes and all. Is this an issue with anyone else and their 870?

Any suggestions in the same price range that typically carried at most sporting good stores?

Read post #6. Seems a few guys have issues. You may be able to correct this by making sure the front blade is as far forward as you can get it and make sure the rear ramp is setting forward of the rear taper of the rib.
