Thanks, I have a rail that looks like the same length as the Ultra rail, but lacks slots in the middle and has a "tightening pin" near the end that screws down from the top side of the rial to contact that barrel underneath, in addition to the regular mounting screws. I think it will work well on my 44 mag Talo barrel.
I have to face it, as much as I love peep sights, and as handi as my 18.5 inch Talo 44 mag is, I will have to scope it. My eyes are no good at seeing sights anymore. So I want as small and unobtrusive a scope as I can get for a reasonable cost.
