Uses same battery as Aimpoint. Newer model that sits centerline over receiver cover. Has reticle similar to EOTech, i.e. large outer ring with tiny center dot. With battery on center dot is red, if battery fails center dot is black (kinda like the Leupold CQT). For pics see Freedom Optics and it's the model with the V-clamp.
This sight is brand new. Sold the AK now I'll sell the sight seperately. Freedm Optics has them for $279.95 plus shipping. I'll sell for $260 shipped.
