I use an EOTech and love it. I've been using them since 2007. I prefer the D1 reticle over the A65 but I can't get the D1 anymore from EOTech. I currently have the OPMOD EOTech EXPS2 on my Sig 556 SWAT Patrol.
I just bought an eotech testing the waters tomorrow, i bought the zombie one just cause i liked the reticle
