Well, I sold almost all of my leupolds for Burris scopes in Signature series. I think the Burris is clearer, and brighter. Leupold is a name,,....a name that most folks follow with no research at their disposal. Burris has the same warranty, with IMHO better glass.
My MK IV leupolds were sold to make way for Nightforce NXS's,..another great decision on my part. Don't buy a name,...buy a product.
Burris signature beats VX III hands down, for less money. NXS beats the MK IV hands down,..for only a little more money. The Leupy boys better get on the stick, or keep hoping people blindly choose a name from the past. Their quality has a long way to go to get next to some of their competition that has underpriced them and provided a coparable or better product.
