I really like it - Trijicon RM04 RMR Dual Illuminated 1x16 mm 7 MOA Reflex Sight

I have both an rmr06 and this dual illuminated 7moa amber dot model as well. I really like the dual illuminated, like other reviews have said, if you are in a dark room and looking into a more well lite area, especially using a high lumen light, the dot will wash out. But hey, thats what your irons are for. The fiber optic works great and its stupid bright in the day time. That will never run out. If you want it, just buy it. I dont regret it one bit.
