For ME---I can't stand the Trijicon's reticles. Maybe that would change if I ever actually used one and shot some with it, but I'm still a loss as to where the bullet impact would be with their reticles.
You are going to get the "Ford vs Chevy" debate when it comes to red dots. Again, everyone like this or that for xyz reason. From everything I've read, Aimpoints get the high marks. I've got a friends EOTech, but I haven't even mounted it on my AR yet. I like the fast aquisition EOTechs bring but I DO NOT like the fuzziness/blurriness they have. The only thing you can change is the intensity of the light. With a $500+ sight I find this UNACCEPTABLE. Would it really matter when killing zombies? Probably not, but with others out there, I seriously doubt I get an EOTech unless they clear up their reticle.
I was actually thinking of getting a M223 Nikon scope thats ballisticly dialed in for the 5.56/.223 round. I was also considering putting a "Red dot of my choice" on the side. Yea, I'd have to hold it "gangsta style" for close encounters, but I feel that this would give me the best of both worlds. I would have the capablility of long range and if a Zombie snuck up on me, I just tilt the AR to the left, look thru the red dot and BAM....dead Zombie! I think I saw in some magazine someone having an EOTech on the side is what gave me the idea.
I'm most likely gonna get a Vortex Sparc or Strikefire for $$$ reasons. But I've heard good things about the Sparc. I'm waiting on SVTs review of the Strikefire to see his thoughts.
These are just my thoughts, hope it helps---Bboy623
