Angus how can you get a MK 4 for $200 bucks cheaper?Ok so when a Bushnell crosses the border its twice that price? And a Leupold isn't? Dang can you get me one of those MK4? Any how I have the 2.5x16x50MM but not tac. Its great glass I wear glasses and I'm 51 I can't really tell the difference between this and a scope that cost twice the price?
