It's still new but quality looks good - Vortex Spitfire 3x Prism Scope w/ EBR-556B MOA Reticle

I haven't taken it to the range yet so I'm not sure of the "zeroing". I checked out the Burris edition of this, which was nice but I recently started getting into vortex optics and found them to be pretty fantastic. The eye relief works great and the illumination is just right too, it has hash marks for ranging & zeroing out to 500 yards, the lions covers work great and can be removed if you wanted too. The caps are also tethered to the unit so you won't be losing those. The last thing is the battery for illumination is a standard 3032.
