Almost good! - AT3 Tactical 3x Prism Scope with Illuminated BDC Reticle

First off its built very well, but the riser is a bit too short and as you can see its built into the optic. Second the battery is dead when you pull it out to use it every time even with the illumination turned off while not in use. Everything else is good. I would not purchase this again since the illumination is basically useless since you have to remove the battery when not in use unless you want to replace it every time you want to use it. Also, have to bend neck in uncomfortable position to get low enough behind the sight to see through it properly. This may not be a problem for a smaller than average person though. My suggestion is spend a little more and get a Primary arms, or Vortex Prism scope.
