It is one of the clearest optics I've ever looked through.
These are currently being used by the likes of SO19 marksmen and other specialist units within the Uk.
These are very rare in the Uk, so grab one while you can.





Here's the leupold blurb on it.
The Mark 4® 1-3x14mm CQ/T® is a revolutionary optical sight for firearms such as the AR-15 and M16, combining the strengths of a red dot sight and the flexibility of a variable power riflescope. Just as important, the reticle is always visible, with or without batteries, so you’re always prepared. The CQ/T is also becoming a fast favorite with competitive shooters who appreciate its unique close and long range capabilities.
This coating on the exterior lenses gives you the ultimate in abrasion resistance and light transmission. The result is a flawless sight picture over a lifetime of hard use. DiamondCoat™ has made a difference in battle; now it can make a difference where you hunt.

Generous Eyebox
The generous eyebox makes it faster and easier to get your eye behind the riflescope and achieve a full, clear sight picture. Setting up for longer shots you'll appreciate the flexibility it affords, and in close up big game or dangerous game situations the quick target acquisition will be the difference maker. At high power, the longer eye relief and more generous eyebox gives you incredible head position latitude and an improved sight pictue that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.
