Would any one suggest buying a vortex strike eagle a friend asked me if they are any good since I have mostly vortex optics, but this is one I don't have yet I have been considering one for an ar10 if I decide to build one in the future. So far I have not had any issues with vortex other than ones I caused my self by dropping my rifle. Some of the reviews I read said it's slightly better than the crossfire 1-4.
