Hi,
I am trying to find open sights that would fit on my little multipump Bowkett carbine.
It has three barrels (short and long .22", and .25").
The outer diameter of the barrels is 0.5" (12.7 mm), but the long .22" has a slimmer end with a diameter of 10.5 mm.
The dovetails is 10 mm.

I think it would be easiest to find a slide on front sight, and a rear sight that would fit on the dovetails.
Perhaps someone has a tip.
I will try a HW77 rear sight for 11 mm dovetails, but I'm pretty sure that tightening it still won't grip the 10 mm dovetails.

Many thanks,
Louis
