The following are my thoughts on the CQ/T...and there is more dicussion on this subject on another thread "ACOGs vs. CQ/T", which I just brought back up to the top, it's worth reading..
I had read many good things about the Leupold CQT sight and got to handle it extensively at the SHOT SHOW. Here are my thought on the Leupold CQT:
The things that I didn't like about the Leupold CQT sight is that it was too big, it was too heavy, why would anyone need a rail system on a scope is beyond me (unless you are a professional mall ninja), it was too long (with a close quarters battle sight you want the ability to mount the sight far foward), the battery only lasts 7 hours, the eye relief was extreemly short for a CQB sight, the field of view was way too narrow, it costs over $700, the CQT has a "dot inside of a circle reticle" and with the narrow field of view it made the field of view too cluttered, ect, ect, ect.
With a CQB sight you want a small, lightweight package that you can far from you eye so you can see what is going on around you. The Leupold CQT is built like a long range scope (ie long, heavy, shorter eye releif), but it really wouldn't work well as a long range scope either because it only 1x - 3x.
I don't want to bash Leupold because I really enjoy their products. With the CQT sight, there was not a lot of thought put into the product or it was made by someone who didn't know what the end user needs in a close quarters battle optic.
If I were looking for something with no magnification I would go with something like the Aimpoint ML2 (battery life in the 100s to 1,000s of hours depending on setting) for around $300 or if I were looking for something with some kind of magnification I would go with something like the 2x or 3x mini ACOGs for around $500.
Basically, the Leupold is the wrong tool for the job, it's just not pratical and has all the wrong features. Just my .02 on the Leupold CQT.
I would highly recommend the Trijicon ACOG TA31, it is the same size as the TA01, but has all the same features as the TA11 such as the BAC, ect. The TA31 is an outstanding scope for close quarters work. The reticle is very quick and easy to pick up and track.
