I bought one of these Fullfield scopes a few months ago with the E3 reticle in SFP, and while it seems like alot of scope for the money and has a "no questions asked" forever warranty, be advised that the E3 reticle is both small and thin. Its floating out in the center of the reticle like a FFP would be on minimum power. In low light, in timber, or even aiming at something dark like a black bear or moose in the middle of the day, I think it might be hard to see and could be problematic.... Great for punching paper though at the range
I have not looked at the BDC reticle.....maybe it is thicker, darker, and covers more of the view? If someone here wants to post up some pics of their BDC that would be cool
