I had my Leupold pop off during a training excersize, so obviously the mount they come with is no good. But I'm happy I found this mount. After instaling it you can instantly feel the difference. It is much more secure, and you can take it on and off in a hurry without fear of loosing your zero as long as you mount it in the same place. A little pricey but a definate must buy for anyone considering using the CQ/T
Pros: Easy to mount, stable base
Cons: Price
