Well, from what I gather, you need a long rail, but if you put the night scope behind the 552, and hit the button, you can see the recticle when you look through the scope. And with the 552, who needs flip up sights?
If the battery fails ???
Not likely, that's why I want the AA model, it uses AA batteries wich have a 600 hour, continuous use, life span in this device, with standard alkaline batteries. Wrap your fingers around some lithium AA's, and you can kick that up to 1100 hours.
(This is at the highest setting of 12 BTW)
But, lets just say the worst happens, the country goes into civil war, hell brakes loose, the lanscape is turned into a lawless wasteland, and you are ready with your little arsenal. But, the batteries just went dead on your EOTech scope. You might have dificulty finding a type N battery, but you opted for the AA model, it was a little more, but all you have to do is crack open the nearest remote control, and you have new batteries. :twisted:
