Short barreled shotguns

[Painkillers]

Fella's I'm looking for a solution to a problem.

I have a few short barreled shotguns. Mossbergs are drilled and tapped, Wingmasters (older ones) aren't, and all of them hit ridiculously high at 25-50m. I've tried the oversized front bead on the Mossberg, and it helps but I still have to hold well under 6 o'clock in order to hit bulls w/slugs.

What is the best shake awake, etched donut of death reticle (in the event the batt dies), and lowest mount available for these shotguns?

Internet pic for attention. (BTW, I hate how far forward and high this sits. Chin weld. So, an improvement on the pic would be appreciated.)

The original Vortex 1X prism has low mounts and a donut of death.... around $200 used.

I doubt it's much lower then the one in the picture so your probably looking at adding a cheek pad of some sort.

Scalarworks makes a low mount for red dots.

On one of my short SGs I just glued a couple 1/2" long pieces of a finish nail on the ribbed 'sight plane' to create 'rear dots'. They're about 1/4" apart and gives a reference like the dots on pistol rear sights and then center the front bead. I recently bought a piece of fibre-op and may replace the 'nails' with that, but the nails are shiny even in low light where the FO would not be as visible? And No need for chin-weld.
And if you're set on a red-dot, maybe just eliminate the mounting base and epoxy one in place. I'd try it with some adhesive that's easy to remove and Not 'overload' on the epoxy. You may not want it 'forever'.
