It is a 1-4 X 24 with what they call the TMCQ (MRAD) reticule.
The mount is also from Vortex, and includes a 20 MOA tilt.
The TMCQ (MRAD) reticule is illuminated, with lines for quick holdover and windage corrections.
TMCQ stands for Tactical Milling Close Quarter. I have found it very simple to use from very close range up to 200 yards. I have not tested it farther yet.
The best demonstration of how to use the reticule is this image published on ar15.com.
Each click on the turret moves the reticule 0.2 mrad.
The red line on the caps is great to indicate 0 position. It allows for a quick return to 0 after adjustments were done to the turrets.
The illumination turret has off positions between each setting. This illiminates the need to have to dial down each setting to turn if off. A great feature IMHO.
