"EOTech is the manufacturer of both sights. Years ago before anyone had ever heard of EOTech, Bushnell signed a deal with them to market their product with Bushnell's name on it. Later EOTech decided to market their product along side Bushnell using their own name. Bushnell and EOTech had a little falling out and have now decided that Bushnell will market to hunters and EOTech will market to police and military.
They are identical in performance and specs. The EOTech tactical models have a roll bar and night vision capabilities."
