As I'm putting together a new build, I found myself wondering why these optics are so scarce. IMO, it's the perfect mag range for blackpowder hunting, long range stuff aside. Leupold seems to have discontinued their 2.5-8 VX3i. Burris Fullfield 2-7 is a goner. Vortex Diamondback and Viper models are both discontinued. Considering how quickly they always get snapped up in the classifieds, there must be a decent market for them. So why do they seem to be going by the manufacturing wayside?
