Ithaca receiver sight - am I making problems?

[Dark Alley Dan]

Gents:

Please forgive the cross-post - I'm not getting anywhere in the Shotgun forum with this one, and it really is more of a gunsmithing question anyway.

My bear-in-the-tent M37 is about ready to go, but I'm still working with the bead alone as a sighting mechanism. I'd like to take the advice of Col. Cooper (RIP) and install a ghost ring rear / front post set up.

The ring installs on the receiver, the post at the end of the barrel (unsurprisingly). The barrel will be removed with some frequency. This will, naturally, change the relationship between the two sights, potentially every single time I whip the barrel off and on. The relative movement between the two will be minor - my 37 is solid, and returns to pretty much the same spot every time. However, there's bound to be some wiggle.

My question: will there be enough wiggle to worry about? I can also consider an express sight / front post setup, but would prefer a ghost ring for the sake of speed.

Anyone have any experience? How about recommendations for sights?

Thanks, gang.

How big is your tent?

Haw!

Assume a very long tent - 75 to 100 yards...

All shotguns that have "take down" barrels are subject to some impact shifting when taken down and put back together. What I did with my 37 was make two small marks. One on the top of the receiver and one on the top of the barrel. I called these reference marks and always alligned them when putting the barrel back on. It works. Be sure to sight the gun then make the marks. They can be very small and hard to see by anyone but you.
