Homemade-ish ghost ring, need some help.

[Beer_drinker]

I found a nifty flip-up in my junk box that will be going on a shotgun, i'd like to transform this rear notch sight into a ghost ring but i've never tried ghost ring sights before so I have no idea what i'm doing...

I could cut away with trial and error but this means driving to and from the range until I get it right which would be time consuming, so if someone could please spare a few details of your setup... I would be most estatic.


A few Q's for the pro's if I may...

1)Rough estimate of size and thickness of ring?

2) On a mossberg w/18" bbl or similar sized shotgun, how high should the rear ring be sitting on the receiver? How high does the front post ride?

3) How far should the ring sit from your eye

Thanks for taking the time to read and hopfully resond.

The ring should be as close to your face as you can get it. If it doesn't look fuzzy when you mount the gun it's too far away. Thickness doesn't really matter. I'd want 1/4" at least for stiffness.

Is this for slugs or birds.

If for birds, you'll want to take material off the outside of the ring too so you have a clear line of sight around the bird to be able to lead properly.

Also, the POI will change depending on choke and shell selection so you'll want to use your regular hunting ammo and choke when you do this little test. If your POI changes later down the line due to changing something, you can always change or file your front bead.

I think you might need a taller front post by the look of that device... I think the flip up will mount too high.

Anyway, here's how to check. Find the POI of your gun lining up the bead with the notch sight. Aim for the center of a dot on a tall sheet of cardboard and fire a group or 1 shell. 10 yards would be a good distance to work at. You'll hopefully be high. If you're low or close, it ain't going to work without shimming the flip up up or getting a shorter front post.

Divide the distance to the target by the front-rear sight distance. Divide the amount you were high by the number you just calculated. This is how much below the notch the center of your ghost ring needs to be mounted.

For example, if you're sights are mounted 20" apart and you're shooting at a 10 yard range, you want to divide the amount you're high by (10*3*12)/20 = 18. If you're 9 inches high, you'll want to make the center of the ghost ring 1/2" below the notch.

Drill a very small hole (a cordless drill at the range can save you an extra trip here) and use it as a peep sight to test out your measurement. Move the hole if you need to.

A good size ghost ring for bird hunting might be 1/4" to 3/8" For slugs, maybe 3/16" to 1/4"

Use a really sharp drill bit to drill out the pilot hole. Use a file to round the outside corners so the "ring" doesn't shroud your view too much.

Good luck
