Easy to adjust the tension. Be careful not to crank it down too tight or you will just defeat the purpose of having a quick release mount—you could end up needing a tool to pry open. I have mine set to where I can unclamp it by hand but it still holds securely—rock solid. It's a little more compact than Trijicon's standard TA51 mount. I have the tension lever on the ejection port side to keep the protrusions all on that side of the rifle. It works well and doesn't interfere with ejecting cartridges. Overall, I like the mount and would recommend it.
