That does not look all that sturdy to me; I would either change to a Losmandy width dovetail or upgrade to a better quality Vixen style
The mount must accomodate? the scope, not the other way around.? How am I going to use it on my AVX if I put a Losmandy shoe on it?
It is stable enough once you know it.? Now that I am warned I check and double-check.? Not worth spending money replacing the saddle, I certainly should not have to.
