Another reflex vote. Really light and unmatched speed. I'm running 4 FFs on turkey rigs including the SA459 you speak of.

Not a big fan of the taller mounts unless speaking AR. Is the riser removable on the Meopta?

I prefer 336 mounts, but the 459 has a round receiver. A pic mount works well with the included base. I actually like the base on the 2016 459 as it has a deep channel designed to be used as open sights with the bead if the optic were to fail in the field.
