Back on topic, the Trijicon Tripower is pretty sweet! Kinda funny looking, but pretty amazing how it all works. Talk about backup power!!! I was going to get an Aimpoint CompML3 or some such model for my .50Beowulf. The Eotech had a lower profile I think, and surprisingly was cheaper. I liked the "scope" look to the Aimpoint, but I liked the compact nature of the Eotech. The Eotech has stood up to the .50Beo recoil just fine too.
