• 8-34x magnification
• 56mm objective lens 
• 30mm tube diameter

• 12.5-3 feet Field of view at 100 yards
• 45 MOA total elevation and windage adjustment

• First Focal Plane (means easier judging size and distance through the scope at varying magnifications) because the reticle enlarges as one increases the magnification.  For example, the distance between Mil-dots (or MOA) will cover the same distance at 8x as it does at 24x.  No need to do any math figuring out what power one is on, etc.
